* 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
* remove getSnapshotBeforeUpdate from status
* remove componentWillUnmount from status
* persist last-intersected status update and restore when ScrollableList is restored
e.g. when navigating from home-timeline to a status conversational thread and <Back again
* cache currently-viewing status id to avoid calling redux with identical value
* refactor collapse toggle to pass explicit boolean
* Fix more visual issues with the audio player
- Add horizontal baseline in the middle of waveform
- Fix audio player colors in light theme
- Use audio element instead of web audio API
- Do not render any bars until the file is loaded
- Do not allow interactions with waveform until the file is loaded
* Fix code style issue
* Add audio uploads
Fix#4827
Accept uploads of OGG, WAV, FLAC, OPUS and MP3 files, and converts
them to OGG. Media attachments get a new `audio` type. In the UI,
audio uploads are displayed identically to video uploads.

This reverts commit c53d67326201b2061990b1874a3547c3647f50d2.
* Fix null error in status component when determining showMedia state
Also update the showMedia value if the status passed to the
component changes
* Refactor media visibility computation into a defaultMediaVisibility function
* Fix default media visibility with reblogs
* Add blurhash
* Use fallback color for spoiler when blurhash missing
* Federate the blurhash and accept it as long as it's at most 5x5
* Display unknown media attachments as blurhash placeholders
* Improve style of embed actions and spoiler button
* Change blurhash resolution from 3x3 to 4x4
* Improve dependency definitions
* Fix code style issues
* Add polls
Fix#1629
* Add tests
* Fixes
* Change API for creating polls
* Use name instead of content for votes
* Remove poll validation for remote polls
* Add polls to public pages
* When updating the poll, update options just in case they were changed
* Fix public pages showing both poll and other media
* Avoid two-step rendering of statuses as much as possible
Cache width shared by Video player, MediaGallery and Cards at the
ScrollableList level, pass it down through StatusList and Notifications.
* Adjust scroll when new preview cards appear
* Adjust scroll when statuses above the current scroll position are deleted
* Refactor uses of icons to an Icon component in web UI
* Refactor options passed to the Icon component
* Make tests work with absolute component paths
* Revert "Fix some icon names changed by the Font Awesome 5. (#8796)"
This reverts commit 3f9ec3de82.
* Revert "Migrate to font-awesome 5.0. (#8799)"
This reverts commit 8bae14591b.
* Revert "Fix some icons names, unavailable in fontawesome5 (free license). (#8792)"
This reverts commit b9c727a945.
* Revert "Update the icon name changed by the Font Awesome 5. (#8776)"
This reverts commit 17af4d27da.
* Revert "Add bot icon to bot avatars and migrate to newer version of Font Awesome (#8484)"
This reverts commit 4b794e134d.
This includes clicks on hashtags, mentions, display names and media in the
timeline; and usernames in reply-indicator, detailed status, and the boost
modal.
* Add keyword filtering
GET|POST /api/v1/filters
GET|PUT|DELETE /api/v1/filters/:id
- Irreversible filters can drop toots from home or notifications
- Other filters can hide toots through the client app
- Filters use a phrase valid in particular contexts, expiration
* Make sure expired filters don't get applied client-side
* Add missing API methods
* Remove "regex filter" from column settings
* Add tests
* Add test for FeedManager
* Add CustomFilter test
* Add UI for managing filters
* Add streaming API event to allow syncing filters
* Fix tests
* Fix: Switching between composing direct message and mention from menus
Previously clicking "direct message" followed by "mention" resulted in the composed status staying as "direct", along with weird spacing of items in the text area. This attempts to fix that.
* Fix: Add missing proptype check for onMention in Status component
* Add the ability to send a direct message to a user from the menu on Statuses
* Add space between "Embed" and "Mention" on expanded statuses menu
* Responsively enforce 16:9 ratio on all media thumbnails in web UI
Also change video player behaviour to "contain" rather than
"cover" videos that don't fit the ratio, unlike images and GIFs,
it's expected that a video is shown fully.
* Fix spacing issues and remove floor
* Remove floor
