**This option is not recommended as it completely obliterates all chances of being able to support someone with a broken room list. It is intended for specific testing scenarios only.**
The room list does a hefty amount of work, so instead of blocking the event loop with a `/sync` request and a bunch of room updates (as we can get multiple per sync) we can instead run it over several smaller tasks. The smaller tasks help the event loop do other things between our tasks, ensuring we don't inadvertently block the UI from rendering too slowly.
On my account and machine, this cuts the time to render in half (~30ms, down from ~60ms) .
The core of this is in the MarkedExecution class, with the remainder of the commit ensuring that the right marks and triggers are in place to do the firing.
Because everything is async/await and run through the RoomListStore, we don't have to worry about self-fed updates in the algorithm classes. This also means we have to trigger pretty much all the time.
Changes to tag ordering / list sorting get hit through two paths, so we mark before we do a bulk update and otherwise assume the call is coming in from outside.
Known issues:
* Causes scroll jumps when the button gets added to DOM
* Resize handle is invisible when there's a show more button
TODO:
* Clean up comments
* Clean up useless code (all the padding stuff isn't needed)
For new rooms, we need to append to our list of known rooms. For tag changes, we need to be sure to update our cache when the tag can reasonably be assumed to have changed.

We were receiving a read receipt before a room object, leading to the algorithm to assume the room is archived (no membership), which was causing later index issues when the room tried to get moved from archived to untagged.
To prevent this, we just ignore nonsensical updates.
Previously we were creating a notification state whenever we needed one, which was leading to hundreds of listeners even on a small account. To ease the burden, and reduce the load of having to wake so many listeners, we now record a single listener for each tag ID and room combination.
This commit also introduces a number of utilities to make future notification work a bit of an easier transition, such as the `isX` and `hasX` getters on the new NotificationState abstract class. Similarly, "snapshots" have been added to reduce code duplication between different kinds of states checking for updates.
The ListNotificationState is now heavily tied into the store which offers it to help reuse the cache of room notification states.

This is more general maintenance than performance as the RoomList doesn't need to be generating layouts for the sublists, and it certainly doesn't need to be creating a bunch of extra ones.
The sublists are perfectly capable of getting their own layout instance and using it, and we are perfectly able to limit the number of these things we create through the session's lifespan.
In this demonstration, we remove the cutting line (as it collides with the tile in a weird spot) and instead replace the tile with a placeholder when the text is about to collide with the avatar in the tile. We use a `round()` for this because through some amazing coincidence the collision happens at 0.47, which is close enough to 0.5 for people not to notice.

Rooms transitioning between multiple states are often at risk of going missing due to the sticky room handling. We now protect that transition by bluntly ensuring the room can't go missing, and by always ensuring we have an updated reference to the room.
react-resizer appears to be okay at tracking state, but it often desyncs from reality. re-resizer is more maintained and more broadly used (160k downloads vs 110k), and appears to generally do a better job of tracking the cursor.
The new library has some oddities though, such as deltas, touch support (hence the polyfill), and calling handles "Enable".

We read/use the options in multiple places, and those places were not in sync. Now when algorithms change and on initial load, both will come to the same conclusions about how to order & sort the rooms.
This fixes a case where a user accepts an invite, which causes a tag change, but the room stays stuck in the invites list. The tag change additionally gets swallowed when the user moves away, causing the room to get lost.
By moving it when we see it, potentially during a sticky room change itself (though extremely rare), we avoid having the room get lost in the wrong lists. A side effect of this is that accepting an invite puts it at the top of the tag it's going to (usually untagged), however this feels like the best option for the user.
A rare case of a tag change happening during a sticky room change is when a leave event comes in for the sticky room, but because it's come through as a tag change it can get swallowed. If it does get swallowed and the user clicks away, the tag change will happen when the room is re-introduced to the list (fake NewRoom event).
Plus a bunch of logging.
This fixes a case where switching rooms would cause the last room you were on to disappear due to an optimization where known NewRoom fires would be translated to tag change fires, which wouldn't re-add the room to the underlying tag algorithm.
By tracking the last sticky room, we can identify when we're about to do this and avoid it.
This commit also adds a check to ensure that we have the latest reference of a room stored as rooms changing from invite -> join change references.
This commit additionally updates the PossibleTagChange handling to be faster and smarter, leading to a more stable generation of the room list. We convert the update cause to a Timeline update in order to indicate it is a change within the same tag rather than having to jump tags. This also means that PossibleTagChange should no longer make it as far as the underlying algorithm.
New logging has also been added to aid debugging.
