Each action is printed twice, indicating that the MediaSession's actionHandler ran twice for each action. 1734329 1 jean-yves.avenard 2021-02-28 21:04:55 -0800 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 1734331 2 jean-yves.avenard 2021-02-28 21:20:48 -0800 This only occurs if the GPUP is enabled. 1734332 3 webkit-bug-importer 2021-02-28 21:21:22 -0800 <rdar://problem/74853506> 1736105 4 jean-yves.avenard 2021-03-04 16:43:08 -0800 *** This bug has been marked as a duplicate of bug 222759 ***
