I see this has been reported before after a bit of searching, apparently this is a limitation of X11 ?
See https://bugs.kde.org/show_bug.cgi?id=442426

Although this is not with function keys but with dedicated keys for controlling brightness and volume.

Yup, this is an unfixable problem in X11. It's already both fixable and fixed in the Wayland session. One of the reasons why Wayland was created was to be able to fix bugs like these. :)
