Touchpad "Disable while mouse is connected" does not work

Help

I have an Framework 13 with an Ryzen 5 7640U CPU with KDE 6.3.5 on Arch.

I want to use the “Disable while mouse is connected”, but it disables the touchpad even when there is no real mouse connected:

I disabled all the displayed devices in the image, but it still disables the touchpad.
No idea what the first two are, they are probably remnants from older devices.

Hi! For what it’s worth, the upstream libinput component implements features like this, which are then configurable through Plasma.

It looks like you’re running into a known issue with how libinput identifies an “external mouse” in order to trigger disabling the touchpad: Better identification of non-mouse devices is needed
