STR: - Open https://googlechrome.github.io/samples/media-session/video.html - In the Now Playing menu, click on Pause, then play - In the page, we can read > User clicked "Pause" icon. > User clicked "Pause" icon. > User clicked "Play" icon. > User clicked "Play" icon. Each action is printed twice, indicating that the MediaSession's actionHandler ran twice for each action.

Additional unexpected behaviour. When click on Pause via a BT headset, the current content is briefly paused to be resumed right away and we can see in the console: > User clicked "Pause" icon. > User clicked "Play" icon. It works as expected in STP, Chrome or Firefox. Wrong behaviour showing in ToT's MiniBrowser

This only occurs if the GPUP is enabled.
