SUMMARY
Using Plasma 6.6 Beta windows setting the "Sticky" Window Hint does not result in the window appearing on all virtual desktops.

STEPS TO REPRODUCE
1. Launch conky with the following included in the conky configuration
    own_window_type = 'normal',
    own_window_hints = 'undecorated,sticky,below,skip_taskbar,skip_pager',

OBSERVED RESULT
conky window is only present on one virtual desktop 

EXPECTED RESULT
conky should display on all virtual workspaces in the same way it would if a custom rule was setup to display on all virtual desktops.

*** Note This has the patches from https://invent.kde.org/plasma/kwin/-/merge_requests/8602 also applied but I don't think that is causing the issue. 


ADDITIONAL INFORMATION
This issue can be worked around by setting up a manual window rule to show the window on all virtual desktops. But this should be doable automatically based off the window rules.

This works fine on other Desktop Environments such as Enlightenment.
