OK, no problem, of course.  There are other bugs to focus in the

I see I failed to CC people that participated in this report. Sorry,
doing that now.  For reproducing, the recipe given by Stefan is pretty
good, but I would like to add that in my experience is better to make
the repeated clicks as if you wanted to double click, but maybe not so
fast.

Try to not move the mouse, and if the option doesn't toggle, wait.
There might be something in the echo area like:
double-down-mouse-1 double-mouse-1-
