Grab and move blocks some shortcuts

### Microsoft PowerToys version

0.99.0

### Installation method

PowerToys auto-update

### Area(s) with issue?

Grab And Move

### Steps to reproduce

I have a global shortcut (via AHK): `ctrl` + `shift` + `alt` + `q`. It runs some process, nothing to do with PowerToys. If I press this shortcut *starting with the alt key* while Grab And Move is enabled, it doesn't work. If I don't do alt first, the shortcut works.

### ✔️ Expected Behavior

It should listen for 'alt', that's fine, but if other keys are also pressed it shouldn't get in the way.
Curiously, other shortcuts like `alt` + `f12` work fine.

Start by reproducing the shortcut conflict with Grab And Move enabled, using the Alt-first Ctrl+Shift+Alt+Q sequence described in the issue. Locate Grab And Move's global shortcut handling and compare it with the reported Alt+F12 behavior. Done means the external shortcut works when the other keys are pressed, while Grab And Move continues to handle its own shortcuts.
