SUMMARY

	The native window border renders far past boundaries of GTK 3/4 window border when noborderrule is set to 2 (Force Always).

STEPS TO REPRODUCE

	1. Create a KWin Rule.
	2. Set "No titlebar and frame" to "On" + "Force" (noborderrule=2)
	3. 

OBSERVED RESULT

	The native window border renders far past boundaries of GTK 3/4 window border.

EXPECTED RESULT

	The native window border should render around the GTK window border as it used to (or better yet, replace it, but that's infeasible and an FR anyway).

Note that this used to not be an issue, recently. It was a regression introduced approximately 1 year previous.
