Not by that specific bug above, no. Time to file a bug against libinput, I
guess.

Note that the libinput debug-events output may be a false positive, you'd
have to keep it running across the suspend/resume cycle to have it trigger
the same issues. If you start it once the bug occured, you'll have missed
the trigger.
