Brush menu moves by itself in WMR

[AdrianTheFrog]

When using WMR as an OpenXR runtime, the brush menu moves when not pressing any buttons. In right handed mode, it automatically moves to the front, while in left handed mode it moves to the back. It only moves when the pointer is pointing at the brush window. This fixes itself when using SteamVR as the default OpenXR runtime, but this comes with more performance overhead.

Hi, I will try to look into this, but please note WMR is no longer supported since Microsoft removed it from Windows 11. My personal rig updated to that version, so it's a bit hard for me to test!
