Fixes #6056

* NavLinks with activeclass instead of Link in actionbar to highlight active tab

* highlight border-bottom in action bar consistent to public view

Mastodon converts all Emoji to images, whether they have a VS15 after
them or not, but leaves the VS15 in the string, which is displayed as
a black box in Safari.

* Fix the display of missing lists

See #6786 -- this fixes part of the issue pertaining to lists that don't exist. I copied the Column being returned from the missing status logic, which works fine. Prior to this, the missing lists logic would generate a column with no back button and with a broken layout. This doesn't fix the broken display of missing accounts -- the column construction pertaining to that logic happens in multiple external functions.

* import ColumnBackButton

missed the import with the first commit

* Add alwaysShowScrollbar prop to ScrollableList

* Fix followers/follows layout issues from #8418

that favourited toot, follow requests, followers of given user, user's being
followed by given user, lists, muted users, toots' boosts.

Switched from using ScrollContainer to ScrollableList and/or added empty
message's text.

* Add title to video, matching aria-label.

* Give focused status a sensible aria-label for screen readers

Fix #8192

* Use content warning in aria-label unless expanded

Fix #4485

* Make dropdown animations respect their placement

Also fix the corner radius on the privacy dropdown button when using top placement

* Fix code style issue

Fix #8274

Fix #8269

This includes clicks on hashtags, mentions, display names and media in the
timeline; and usernames in reply-indicator, detailed status, and the boost
modal.

* Show exact number of followers/statuses on export page/in tooltip

* Fix tests

* Prevent default event handling when clicking on the video position slider

This prevents accidental text selection when clicking on the position slider.

* Fix bug when clicking on video position slider before starting the video

* Slightly more aggressive video preloading

- Preload video metadata if the video is loaded in detailed view, as it is
  likely to get played, and metadata is useful for seeking in the video.
- Preload video data if it's fullscreen as it is extremely likely to get
  played right after being put in fullscreen (although those are two steps).
- Preload video data if the user has clicked the position slider, as the video
  will play as soon as the mouse button is released, and video metadata is
  needed to properly seek into the video.

* Compensate for scrollbar disappearing when media modal visible

Make auth pages backgrounds lighter

* Fix typo

* Remove superfluous span tags

* Make account bar items (except dropdown) flexible to work well with custom CSS

* Fix CSS lint warning (0px → 0)
