Move newly created windows to their last known zone function moves all the windows of the same application to one zone

Microsoft PowerToys version

v0.98.1 - btw I had to write this manually, couldn't copy from PowerToys directly?

Installation method

GitHub

Area(s) with issue?

FancyZones

Steps to reproduce

1. Define three zones.
2. Open a web browser - I used Edge for my reproduction.
3. Move the first window of the browser to zone 2.
4. Initiate an action in the browser that opens a new window.
5. Move the new window to zone 1.
6. Initiate an action in the browser that opens a new window.
7. Move the new window to zone 3.
   --- Assume this is the wanted state ---
8. Close all windows of the browser in the chronologically descending order (the newest closes first).
9. Open the browser again.

✔️ Expected Behavior

At least the first window of the browser opens in the correct zone (2).

❌ Actual Behavior

All browser windows open in zone 3 - the last zone any window of that browser was moved to.

I suggest to allow multiple zones store the same application with another variable like an order or name.

Start in the FancyZones window-placement and persisted-zone handling, then reproduce the listed Edge multi-window sequence with three zones. Trace how each browser window's last zone is stored and restored. Done means reopening the browser restores its windows to their individual prior zones instead of placing all of them in the last-used zone.
