Setting the debug modifier key to a mouse button doesn't allow for switching to the selected gamemode in the gamemode switcher

If you set the debug modifier key to a mouse button, hold it down, and press F4, the gamemode switcher appears, but releasing the mouse button does not switch your gamemode and close the menu.

The gamemode switcher doesn’t seem to recognize when mouse buttons are released. When using the default F3 + F4 key bind, releasing F3 switches you to the gamemode you are selecting. Releasing the mouse button doesn’t do this.

Steps

1. Open the key bind settings and set the debug modifier key to a mouse button, such as Button 4 or Button 5

2. Go back in game, hold that mouse button, and press F4.

You’ll see the switcher appear, but not close unless you press escape.
