Steps to reproduce:

1. Open the Minecraft Launcher to Java Edition
2. Click the play button in the upper right corner to swap from the image to the 'soothing scene video'
3. Go to "What's new" in the lower left corner
4. Return to the play tab

Observed result:
Upon returning to the play tab the 'soothing scene' visuals are gone, but the playback control buttons are still there. Unmuting the music starts it over again without the visuals.

Expected result:
Upon returning to the play tab either the 'soothing scene' visuals are still there and the music continues playing, or either both the visuals and playback controls are gone.
