Description Roke Julian Lockhart Beedell 2025-03-20 21:14:22 UTC 
SUMMARY

QML ComboBox doesn't render ListElement in kcm_kwinrules.

STEPS TO REPRODUCE

1.	Invoke kcm_kwinrules via kcmshell6 or systemsettings.
2.	Create or modify a ruleset.
3.	Invoke a ComboBox.

OBSERVED RESULT

I see some *really* weird behaviour (see the attached screenshots) with the undermentioned logs:

EXPECTED RESULT

They should render.
