Implement KDE's workaround for GTK3/4 to support "Fitts' Law" (i.e. clicking the very top-right pixel of your screen should close a maximized window)

This is most easily confirmed via the program "Archive Manager"—simply maximize its program window and try clicking on the very top-right pixel of your screen (spoiler alert: it won't work).

Note that this does not impact all programs (e.g. Nemo properly obeys "Fitts' Law").

　

Here's the 7.5-year old GTK issue on the subject that, thus far, hasn't really ever gone anywhere:

• https://gitlab.gnome.org/GNOME/gtk/-/issues/583

And the relevant KDE merge request (if it can be called a "request" anymore considering it's been merged) from just a few months ago where they discovered a work-around that could be implemented on their side of things:
