Additional information

Seems to work on mpv's on screen controller.

This is going to need some changes from the mpv side. The problem is actually that the focused property is currently not available when using libmpv. If this was changed so that it can be set by a libmpv client, then we can get this to work by updating the property whenever the focus state changes.
