Also confirmed on:

Fedora 39 KDE Spin VM (latest updates as of Tue 27 Feb 24), running as Virtualbox guest under Windows 11 host;
Fedora 39 KDE Spin VM, (latest updates as of Tue 27 Feb 24), running as Gnome Boxes guest under Ubuntu 22.04 host;
KDE Neon Developer VM, (updates crashing under Discover on Tue 27 Feb 24, but up-to-date prior to that) running as Gnome Boxes guest under Ubuntu 22.04 host.

The bug exists whether Plasma is in a Wayland session, or an X11 session, regardless of whether Num Lock is on or off, in either case.

Implement MouseKeys on Wayland

This allows to move the mouse cursor using numpad keys.

This is an accessibility feature. On X11 this is implemented in XKB, on Wayland we get to do it outself.

It's implemented as a plugin that filters for relevant keys and generates mouse events through a virtual pointer device
