Volume slider can only be clicked (no sliding) when player is enlarged

Steps to reproduce

1. play a song
2. set the view to browsering (minimized player)
3. try changing volume by sliding
4. open the player in large screen
5. try changing volume by sliding

What happens?

Sliding only works when player is minimized. When player is open fullscreen, you can only click the volume bar, but trying to slide loose the focus on the button.

What is expected?

Sliding should works in both case.

Context

Funkwhale version(s) affected: 1.1

On v1.0, I already had the issue no matter the view. Though 1.1 fixed it for minimized player I guess.
