SUMMARY

Enabling focus stealing prevention for element-desktop (installed via arch repos), for example, with Force and Extreme, doesn't prevent it from stealing focus. For example, with Focus Stealing prevention enabled with Force Extreme for element desktop and having it auto start in a separate virtual desktop, it will always grab focus despite that setting. Ignore requested geometry has no effect on this behavior.

STEPS TO REPRODUCE
1. Set Focus Stealing Prevention to Force Extreme for Element Desktop
2. Have element desktop auto start into a separate desktop
3. go onto another virtual desktop
4. Auto start element desktop
5. Observe that the virtual desktop is automatically switched to that of element desktop's despite the setting.

OBSERVED RESULT

Focus stealing prevention is ignored for some apps.

EXPECTED RESULT

I would expect focus stealing prevention to be observed regardless of the app.

Is this app running in XWayland mode? If so, do those high focus stealing prevention modes work when you force it into native Wayland mode by passing it `--ozone-platform=wayland` on the command line?
