This is fixed in 5.16 with the rewritten Window Decorations KCMs.

window decorations kcm on neon dev unstable
Unfortunately it's not fixed if "Titlebar buttons" tab is focused.
See the screenshot taken on neon dev unstable.
Further fixes to default sizes of QtQuick KCM pages were committed. If this is still reproducible with master, please re-open the ticket.
