Select widget eats all mousedown events

Since version 1.10.8 adding a mousedown handler on the Select widget is not possible, see . My guess is this is a bug, because the comment near to the changed code says an expected behavior is that 3. user defined onMouseDown handler fires.

This seems to have been caused by this commit
I tested, and reverting that commit fixes the issue, but I’m not sure why it was done in the first place.

I haven’t been able to create a dojo account to report the issue properly, I would like it if someone could do so.
