FancyZones: Firefox PiP window inherits dimensions from main window resize

### Microsoft PowerToys version

0.100.0

### Installation method

PowerToys auto-update

### Area(s) with issue?

FancyZones

### Steps to reproduce

Resize main Firefox window with fancyzones. The next time a PiP window is opened, it will inherit the resized dimensions of the main window instead of remembering size and location.

### ✔️ Expected Behavior

PiP window will open in the location it was last closed, with the same size. This behavior is observed with the windows-native resize options.

### ❌ Actual Behavior

After using fancyzones to resize main firefox window, the next time a PiP window opens it will be the size of that zone, not the previous size.

No source file, test, or entry point is named. First reproduce the issue in FancyZones on Windows 11 with Firefox PiP, comparing a FancyZones resize with the native resize behavior; done means PiP reopens at its previously saved location and size after the main window is resized.
