Found testing calls between two phones on the Compose call stack:
- The famedly SDK keeps only "important" state in memory for a room that
hasn't been opened, so call memberships of other rooms were invisible:
no ring (it was cleared at once, the call looking empty), no room-list
marker. org.matrix.msc3401.call.member is now important state.
- The incoming-call card closed itself with Navigator.pop when the ring
cleared, which popped the call screen pushed above it on Answer. The
buttons now close the card first, and it closes itself only while it
is the top route.
Tested: a voice call in a room of two (ring, answer, both connected
through LiveKit), and a video call in an encrypted room (to-device media
keys, frame cryptors OK on both sides, each phone showing the other's
video). The web client sees a phone's membership and rings for its
notification.
