lomiri: multi-workspace mode: when coming back from the stage maximized windows get unmaximized, but the WM thinks they are still maximized

How to reproduce this issue:

• Install Debian 13 minimal on physical hardware (e.g. a notebook) or a VM, and run apt install lomiri afterwards. Reboot.
• Enable workspaces in lomiri-system-settings (Desktop & Launcher -> Enable workspace [x])
• Open an application, maximize it
• Go to the stage (mouse pointer, push to the right)
• Go to the workspace part at the top of the screen, click on the bar and Add workspace
• Double click on the right (new and empty) workspace
• Go to the stage again (mouse pointer, push to the right)
• Double click on the left workspace again where you see your app in fullscreen previewed
• Observe the window size change

What you will observe:

• After you have gone back to the first workspace, your previously maxmized app is not maxmized anymore.

What should happen:

• Maximized apps stay maximized

Also:

• Window positions of non-maxmimized windows should not change when changing workspaces
