donotdisturb plugin: "Switch the interruptible windows to normal mode" does not work

[deltragon]

Describe the bug
The "Switch the interruptible windows to normal mode" setting for the donotdisturb plugin is supposed to un-fullscreen a fullscreen window if it is bypassed by the "Interrupt these windows regardless of their state" setting.

This does not work currently. The bypass works, and the break triggers despite the window being fullscreen, but it does not get un-fullscreened.

This only applies to X11 as Wayland currently does not have support for the "Interrupt these windows regardless of their state" and "Switch the interruptible windows to normal mode" settings.

To Reproduce
Steps to reproduce the behavior:

1. Test on X11 (eg. LXQt).
2. Enable the "Do not disturb" plugin.
3. Fill the "Interrupt these windows regardless of their state" setting with an application (eg. qterminal).
4. Ensure the "Switch the interruptible windows to normal mode" setting is set.
5. Fullscreen the application selected in step 3 (eg. qterminal), and keep it focused.
6. Trigger a break (this can be done from within qterminal, ensuring it stays focused).
7. Notice how the break triggers, however the qterminal application stays fullscreen (possibly even covering the break screen).

Expected behavior
The application (qterminal) should be un-fullscreened.

• OS: Any (tested on Debian 12)
• Desktop Env: X11 (eg. LXQt)
