[zero13722]

Description:
Media control in notification panel goes wild by having more than one active Xtra clients.

Steps to reproduce:

• Duplicate and run two Xtra clients (using stock Private/Work profiles)
• Play videos on both apps at the same time
• Media control for both Xtras keep switching their places on their own

Expected result:
It should stand still.

(None of screen operation for the first 6 secs)

i guess the media3 library is doing something crazy like trying to update the notification every second. it doesn't seem to happen with clips
