VRChat prevents using mouse in a second program in gamemode

[Managor]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

If I open VRChat and then open Firefox or Chromium as a second program to fetch a link, VRChat hogs the mouse input. Not sure if this a Steam Input problem or gamescope problem

Steps To Reproduce

1. Launch VRChat
2. Launch Firefox
3. Use the trackpads and triggers to try and move the mouse
