Why when adding a Player.Listener to a MediaController or MediaBrowser the onPlayerErrorChanged has not the same behavior as if it was added on a Exoplayer instance ?

Behavior of Exoplayer:

• Play a item that throw an error
• onPlayerErrorChanged(newError)
• Play other item that doesn't throw an error
• onPlayerErrorChanged(null)

Behavior of MediaController / MediaBrowser:

• Play a item that throw an error
• onPlayerErrorChanged(newError)
• Play other item that doesn't throw an error
• Expect a onPlayerErrorChanged(null) but the callback is never called!

Tested on release : 1.0.0, 1.0.2, 1.1.0-beta01

Test / reproduce the issue

To test the behavior you just have to modify and run the demo-session with this modifications

add in assets/catalog.json

 {
      "id": "video_04",
      "title": "Video with error",
      "album": "Mango Open Movie project",
      "artist": "Blender Foundation",
      "genre": "Video",
      "source": "https://storage.googleapis.com/wvmedia/clear/h264/tears/unknow.mpd",
      "image": "https://storage.googleapis.com/wvmedia/clear/h264/tears/unknow.mpd"
    },

And add onPlayerErrorChanged callback from the Player.Listener in PlayerActivity.kt

override fun onPlayerErrorChanged(error: PlaybackException?) {
    Log.i("MyTag", "error = $error")
    val errorMessage = error?.message
    playerView.setCustomErrorMessage(errorMessage)
}

The custom message is never clear and it will be showed after playing another media item that play correctly.
