[Bug 1545293] [NEW] KDE forgets Caps as Escape keyboard setting

[Stephan Diestelhorst]

Public bug reported:

In the KDE Input device dialog, I have checked

Advanced -> Caps Lock key behavior -> Make Caps Lock an additional ESC

however, the new KDE keeps forgetting this setting when restarting /
undocking.  If I disable, enable and then apply, it works again.  The
setting is always set in the config dialog, but the keyboard is not
configured correctly.

I have attached logs of xev, setxbkmap, and xmodmap for when things are
not working (despite the setting being set) and after I re-apply the
setting as above.  The relevant diffs are these:
