This will show if the call is waiting for media to connect (in practice doesn't actually seem to happen all that often) but also show if the media connection is lost, with the js-sdk change. Requires https://github.com/matrix-org/matrix-js-sdk/pull/2880 Fixes: https://github.com/vector-im/element-call/issues/669
