1.9.0 CastPlayer goes into an idle state when starting new items while casting.

Version

Media3 1.9.0

More version details

Changing the current playing item while already casting causes the player to go into an idle state with no items or playing status while the selected item plays on the cast device.

The player can eventually update with an EVENT_MEDIA_METADATA_CHANGED update or forcing it by moving to the next item in the playlist.
