Room timelines flash raw matrix IDs before showing the profile displayname

[ara4n]

Steps to reproduce

1. Open a largeish room
2. At least some of the senders are shown with raw mxids and default avatars (i.e. without profiles) for a second or so
3. And then the mxids resolve to actual displaynames.
4. Feel unsettled at the clunkiness.

Looks like this:

Outcome

What did you expect?

We should have the correct profiles available to us from the m.room.member events in the room already; we shouldn't be "fixing up" the profiles in retrospect and thus the 'flash of markup' shouldn't be happening.

What happened instead?

flash of raw mxid, which is ugly and clunky and makes everything feel unpolished.

This is a consequence of not including m.room.members in the sliding sync request to reduce its size. We load the m.room.members events upon creating the RoomProxy just before showing the room.

Maybe this will be fixed by having a cache again.
