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".

Fixes https://github.com/vector-im/riot-web/issues/14372
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.
