SUMMARY
I'd like to know the current XKB group ID via the Wayland input-method but cannot do it.

STEPS TO REPRODUCE
1. Configure XKB group layouts for the default session. E.g. "us,de" in /etc/vconsole.conf and /etc/X11/xorg.conf.d/00-keyboard.conf
2. Log into the Plasma Wayland session
3. Keymap icon shows the firsts XKB layout in the Plasma panel . E.g. "us"
4. Click the keyboard icon and the icon shows the next layout. E.g "de"

OBSERVED RESULT
The Wayland client signal wl_keyboard_listener->modifiers() is not called.

EXPECTED RESULT
The Wayland client signal wl_keyboard_listener->modifiers() is called with the updated group ID.

ADDITIONAL INFORMATION
