ADDITIONAL INFORMATION
1-regression; age unknown
2-I tried also in Fedora 36 with 5.24.5/5.93.0 and got a different failure. Instead of xserver then fonts, because Fedora doesn't seem to provide an xserver module, I used fonts then mouse, with the following result:
> kcmshell5 mouse &
> kf.guiaddons: Could not find a suitable handler for "help:/kcontrol/fonts/index.html"
kf.guiaddons: Could not find a suitable handler for "help:/kcontrol/fonts/index.html"
(no kcm mouse window opened)
3-Tumbleweed 20220517/5.24.5/5.94.0 results match TW20220624

Can reproduce:
