Implements Picture-in-Picture functionality for the Electron wrapper to maintain video engagement when users are not actively focused on the conference window. This feature addresses the need to keep users visually connected to the conference even when multitasking.
Key features:
- Automatic PiP mode activation and deactivation based on user interaction
- Displays large video participant's stream or renders their avatar on canvas when video unavailable
- Provides audio/video mute controls via MediaSession API directly in PiP window
- Adds API events (_pip-requested) for Electron wrapper integration
Implementation includes new pip feature module with Redux architecture, canvas-based avatar rendering with custom backgrounds support, and integration with existing mute/unmute logic. Depends on jitsi-meet-electron-sdk#479 for proper user gesture handling in Electron.
It was possible that join can be executed before conference.init have even started or we haven't reached the point ot create the initialGUMPromise. This was causing the following issues:
- users stuck on the prejoin screen
- participants join 2+ times in the call (we have been creating more than 1 local participants from a single page).
