### Steps to Reproduce

1. Open window on workspace 1, make sure it's focused
2. Open another window on workspace 2
3. Turn on "Always on Visible Workspace" window context menu option
4. Switch to workspace 1, window 2 is on top of window 1 despite it being focused before

### Expected Behavior

Such window to act like a normal one, as in, not cover other windows unless purposefully focused.

### OS Version

8.x (Circe)

### OS Architecture

amd64 (on most hardwares)

### Session Type

Classic and Secure Sessions (I have tested in both)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell

```

### Hardware Info

_No response_

The issue names no files, tests, or entry points. First reproduce the workspace-switching case with “Always on Visible Workspace” enabled in both maximized and normal windows, then trace Gala/Mutter’s focus and stacking behavior; done means the window behaves like a normal window after switching workspaces and does not cover the focused window.
