None of those overflow issues are reproduced on the modern message layout- they are specific to the message bubble layout.

Encountered a similar issue during a Community testing session.

1. Have message bubbles turned on
2. Join a video room
3. Have an iOS/Android user start a conference
4. Have them end the conference
5. See the chat window

Expected: no overflows, video conference events display nicely
Actual: read receipts are cut off, conference event bubble is too tight

@frakic that should be fixed with matrix-org/matrix-react-sdk#8470.
