FancyZones

### Steps to reproduce

I just installed it, clicked on FancyZones, clicked on Open layout editor, and the screen showed screen 3 to be very small.

### ✔️ Expected Behavior

_No response_

### ❌ Actual Behavior

### Additional Information

_No response_

Start by reproducing the issue in the FancyZones layout editor with a three-monitor setup, using the reported PowerToys version and Microsoft Store installation. The work is done when the editor gives the third monitor an appropriate display area rather than rendering it very small.
