Thanks for the report. Eg visible in buffer-menu, where mouse-1 does not
sort.

I don't know what's going on here, but it seems to have some relation to
mouse-1-click-follows-link. If you set it to nil, or leave it alone but
make a long mouse-1 click, then it works. Otherwise it calls the sort
function twice as you say.

This seems like something that should be fixed for 24.3.
