Ignore the update that comes in from the RoomViewStore when the
current room changes or we save our scoll state against the new
room rather than the old one.
Fixes https://github.com/vector-im/riot-web/issues/5010
...on room switch. We were setting most of the state in viewRoom,
but getting the current room ID from the RoomViewStore, but this
meant we did one setState from the RoomViewStore updating,
re-rendered and then setState again in viewRoom causing another
render. This just sets the room ID in viewRoom.
onHaveRoom sets some more state (among other things) so putting it
in the setState callback so it could observe the new state caused
us to have to re-render again unnecessarily. Just give it the new
state as a parameter.
Calling just checkFill on DidMount did not initially set the
scrollTop which meant that one back pagination request is always
performed regardless. This meant we would end up rending the
first batch of events, then paginating and re-rendering again
after the pagination got another batch, causing unnecessary render
churn.
to keep the place we're scrolled to in rooms. This mainly eleimates
the extra, superfluous onRoomViewStoreUpdate callback that
happened when the previous room saved back its scroll state.
Moving the scroll state to a separate store means we can have this
not emit events because nothing needs to know when the scroll state
changes.
If the js-sdk had a lot of history in memory for a particular room,
riot would paginate all that history into the DOM and render it
when switching to that room (before then removing it all again).
This obviously made switching to that room very slow.
This was caused by the fact that we relied on the setState that
happens in TimelinePanel after the pagination taking effect such
that ScrollPanel sees that it no longer needs to paginate, but
in some situations (as far as I can see, in electron...?) this
setState would not take effect until the pagination stopped
fulfiling requests from memory and hit the network.
Fix: don't resolve the promise returned by the pagination request
until the setState has actually happened.
Use `react-sticky` to implement sticky date separators. This will pin a date separator to the top of the timeline panel when the separator scrolls out of the top of the view.
A known issue of this is that the spinner, which is in line with event tiles in the timeline, will appear to push the stuck date separator down. In reality the first date separator after the spinner is in line with event tiles and is not stuck because the spinner forces the timeline to be scrolled slightly further down than it would be otherwise. But also, date separators in the timeline (not "stuck") have a greater height.
Ideally the date separator would be suppressed whilst back paginating, but this will cause the stuck separator to flicker on and off. This is why the suppression has been removed.
- this should fix a race where if the 'hangup' arrives hard on the tail of the
Call.incoming, we don't ignore it.
(We still have a problem in that we blip the hangup tone and UI, but that is
arguably a separate problem)
this fixes the scenario of N Member events, then an invisible event
e.g. (m.room.aliases) then more Member events. Pre hide-join-parts
this is how it worked.

the RightPanel will be mounted once we're done doing the first sync, so wait until then and then dispatch a view_user. This is not very nice but it's what we do for view_room.
Adding `override: true` will remove the feature from the labs section, and force Riot to always use the default value (i.e. ignoring localStorage). This is useful removing features entirely when they might be deliberately not working but we still want to do a release.
