That was too good to be true: the problem is back, and I confirmed that
it doesn't appear right after boot but only "after a while".
So far it has appeared after a suspend+resume but not just after any
suspend/resume.

I looked at the dmesg output (see below) of the suspend+resume after
which the problem (re)appeared but couldn't spot anything that seemed
relevant: in that output, there are two rounds of suspend+resume
(delimited by diff3 markers, so I could use `smerge-mode` in Emacs to
look at the word-level diffs 🙂).  The mouse buttons still worked
correctly after the first suspend+resume but not after the second, but
if you compare the two parts of the log, there are virtually no
differences.  🙁

I'm on "testing" so I'm currently on 6.19.13.  Now that I know it shows
up only after a while, I may (re)try bisecting, but the bisection will
be slooow.

The reporter closed it saying that it was a problem on his side, so it
seems unlikely to be related, but thanks for the suggestion.
