From the start, swiping columns was highly unreliable because the logic
could change `ReactSwipeableViews`'s `animateTransitions` property
mid-swipe.
PR #11200 partially fixed this, but at the unintended cost of disabling the
swipe animation altogether.
This PR changes the logic behind `shouldAnimate` to only disable the swiping
animation at the end of a column change not initiated by `ReactSwipeableViews`.

This used to be the case until #13987, which introduced a hotkey to toggle
the Content Warning field.
Unfortunately, MacOS relies on the “alt” key for many things, including
composing text (see #14862), therefore, even if that makes the CW toggle
hotkey significantly less useful, it makes sense to not interfere with
composing toots.

This commit replaces all unnecessarily repeated code for decoding and
embedding blurhash canvases with separate component - <Blurhash>.
Under the hood Blurhash component will use effect dependent on its
props. This gives a few benefits: it will only be re-rendered whenever
the hash or width/height/dummy props update, and will not render if
canvas won't get to the final DOM, because then effect won't fire,
which prevents weird bugs like #14257.
This commit introduces new utility component - ShortNumber. It should
work almost the same way as original shortNumberFormat function,
though it also localizes units and accepts one more prop - renderer.
Renderer is a function that takes rendered short formatted number
and also ready-to-pluralize number to format display result accordingly.
Ready-to-pluralize number allows to correctly select plural for
compactly notated numbers, respecting thousands and other units.
Issue #12451 accurately describes the issue with using raw numbers
when replacing counter with short version. In short, it doesn't work
with languages such as Russian, that require different plurals,
according to the unit number was compacted to.
All previous usages of shortNumberFormat were replaced with new
function, and as it became unused, it was removed to avoid misleading.

Fixes#13573
For some reason (I suspect this may be related to focusing the item before it
got drown by the browser), Firefox scrolls to top when bringing up dropdown
menus with pre-selected items.
This commit uses the “preventScroll” option as, due to the placement behavior,
the menu should be visible anyway and not trigger scrolling.
Fixes#13536
- Expanding a paused video doesn't autoplay anymore
- Default volume level for the expanded video inherited from the original video
Position/playing state/volume are carried over from the original video player
to the modal, but they're not reported back to the modal as it would require
deeper changes.
This commit redesign the polls and increases characters limit for the
options from 25 to 50 characters, giving pollsters more freedom.
Summarizing, the redesign is making the polls more adaptive for upcoming
changes to the options characters limit: the bar, or a "chart", is now
displayed separately from the option itself; vote check mark is moved
next to the option text, making the percentages take less space. Option
lengths are taken into account and text is wrapped to multiple lines
if necessary to avoid overflow.

This two-line change fixes a crash in the front end that occurred
under the following circumstances:
* A server had more than one announcement,
* A user was displaying the announcements, and
* An announcement was deleted (or unpublished, which amounts to
the same thing.)
As might be expected, the bug was caused by attempting to access a
notification using an index value outside the bounds of the existing
announcements. Specifically, in two places. First,
`_markAnnouncementAsRead` attempts to modify announcements based on
the current index. This is what caused the front end crash. Second,
when rendering the `Announcements` component, the code paginates the
announcements and displays the current one. This did not cause a
crash, but caused the front end to confusingly display a blank
announcement (in situations that would have caused a crash) with no
way for the user to navigate back to previous announcements.
This commit fixes both issues by adding a check to ensure that the
code never attempts to access an announcement with an index greater
than or equal to the number of announcements present.

accidentally merged spurious code in https://github.com/tootsuite/mastodon/pull/12661. https://github.com/tootsuite/mastodon/pull/12735 removes the slowdown that this code was trying to solve; and other functionality successfully restores the view state of the list
* Summary: fix slowness due to layout thrashing when reloading a large set of status updates
in order to limit the maximum size of a status in a list view (e.g. the home timeline), so as to avoid having to scroll all the way through an abnormally large status update (see https://github.com/tootsuite/mastodon/pull/8205), the following steps are taken:
•the element containing the status is rendered in the browser
•its height is calculated, to determine if it exceeds the maximum height threshold.
Unfortunately for performance, these steps are carried out in the componentDidMount(/Update) method, which also performs style modifications on the element. The combination of height request and style modification during javascript evaluation in the browser leads to layout-thrashing, where the elements are repeatedly re-laid-out (see https://developers.google.com/web/fundamentals/performance/rendering/avoid-large-complex-layouts-and-layout-thrashing & https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Performance_best_practices_for_Firefox_fe_engineers).
The solution implemented here is to memoize the collapsed state in Redux the first time the status is seen (e.g. when fetched as part of a small batch, to populate the home timeline) , so that on subsequent re-renders, the value can be queried, rather than recalculated. This strategy is derived from https://github.com/tootsuite/mastodon/pull/4439 & https://github.com/tootsuite/mastodon/pull/4909, and should resolve https://github.com/tootsuite/mastodon/issues/12455.
Andrew Lin (https://github.com/onethreeseven) is thanked for his assistance in root cause analysis and solution brainstorming

* Delete display_name method

* Improve styling of poll option checkboxes/radio buttons
* Use more appropriate ARIA roles for poll options
* Allow switching between single and multiple choice from keyboard
* Coding style
* Avoid using .bind()
* Add follow_request notification type
The notification type already existed in the backend but was never pushed
to the front-end. This also means translation strings were also available
for the backend, from the notification mailer.
Unlike other notification types, these are off by default, to match what
I remember of Gargron's view on the topic: that follow requests should not
clutter notifications and should instead be reviewed at the user's own
leisure in the dedicated column.
Since follow requests have their own column, I've deemed it unnecessary to
add a specific tab for them in the notification quick filter.

Fetching statuses from all followed accounts at once takes too long
within Postgres. Fetching them one by one and merging in Ruby
could be a lot less resource-intensive
Because the query for dynamically fetching the home timeline is so
heavy, we can no longer offer it when the home timeline is missing
