Reproduction steps

It is trivial to demonstrate the violation of documented behavior under any app supporting https://developer.android.com/media/media3/session/background-playback#resumption

• Settings
• Sound & vibration
• Media
• Pin media player -> disable (qs_media_resumption = 0)
  The steps above reflect the wording of https://developer.android.com/media/implement/surfaces/mobile#supporting-media:

The playback resumption feature can be turned on and off using the Settings app, under the Sound > Media options. The user can also access Settings by tapping the gear icon that appears after swiping on the expanded carousel.

From this point:

• Force-stop any app playing media
• Restart the phone, if you wish
• Start the phone
• Invoke media resumption by initiating a Bluetooth connection or using a hardware play button

Expected result

Media does not play when the play button is pressed with qs_media_resumption disabled.

Actual result

App opens and media plays, despite the app being killed and playback resumption being disabled.

Media

This is a framework issue reproduceable with any app that implements Playback Resumption, including ExoPlayer.
