The place I wanted to fill is oddly shaped, so I tried using two volumes to help fill it, only to encounter a bug where the media player only turns on when in both volumes at once.
I remember a similar bug happening with sky volumes and wonder if this is similar.
Steps to Reproduce
Overlap two Media Player Volumes connected to the same media player, in my case it was a theater screen, though any should work fine.
What I expected to happen
An extended media player volume.
What happened
The media player only turned on when in both volumes.
