The patch is highly unlikely cause this. I don't think this would even be
fixable in kernel. Keystrokes all follow a different input path nothing
hid-multitouch touches. 
This could be a hardware/firmware issue, you could test running evtest on
keyboard node, if evtest does not list the unregistered keys then the device
didn't even send them. But if it does, then it's likely libinput or the
compositor.

About disable-while-typing being greyed out, that seems to be a libinput issue
and should be reported there instead. Touchpad might be getting set as external
by libinput and disabling the feature.

I'm going to send the patch after slightly revising it upstream, please let me
know if I should add a Tested by tag now.
