Replies to messages sent before the blue "Message history is currently unavailable in this room" warning don't show as replies.

[ara4n]

Steps to reproduce

1. Logout
2. Log in again
3. Have someone send a reply (in an E2EE room?) to a message which predates you logging back in.
4. Nothing shows the message in the timeline as being a reply.

(when trying to take a screenshot of this, after upgrading to build 312, the placeholders were shown however - so either this got fixed in 312, or it's racey. i'd assume the latter)

Example impacted message:

Outcome

What did you expect?

Replies should show a placeholder to the thing they're replying to, even if that message isn't available to the client.

Sorry for a bit off topic. Is there an existing issue for "message history currently unavailable"? Trying to understand how and when this can be resolved.

Cannot reproduce w. the app supporting keybackup now.
