I have reproduced this by checking out the git branch in question and
building it directly, so it was not a side effect of my earlier attempt
(above) where I had backported this to 1.13.3.
The problem can be reproduced very easily: xinit /usr/bin/xev (running
over ssh from another machine, to be able to see stdout)
Move the mouse cursor to the top left (where the xev window is). Click
and hold the mouse button, and keep holding. No output from xev. Now
release the mouse button, ButtonPress and ButtonRelease arrive at the
same time. No touch input is needed to see this problem.
A few churns of "git bisect" later I have tracked this down to:
3e1515898545b0ed9e1f0794800c07061c8c8039 is the first bad commit
