MatrixRTC calls from EXA to EW lead to a call notification popup, with a join button and disappears after a second

[spaetz]

Steps to reproduce

I call from Element X Android v25.06.0 (but same behaviour with previous version) to another account on current Element Web. Both users are in a DM room. For a split-second the notification popup appears in EW with a join button, but it disappears immediately, and there is no ringing.

This occurs 100% of the time. It does not matter whether the new to_device messages are turned on or off in EXA. It also behaves the same in the previous release of EXA (with embedded EC 0.9).

I will send a rageshake and refer to this issue.

Outcome

This is the Javascript console in my Firefox 139 on Debian Linux:
