Description
after some time of working with a dojo-web-app, _HasDropDown widgets seem to be broken.
the drop-downs are closed immediately after showing them.
we can also reproduce this by alternately and rapidly clicking with left/right mouse on e.g. drop-down-buttons.
I attached a small test-page. just click left/right on one of the drop-downs about 20 times, and the whole page is broken. none of the drop downs opens again.
the widget seems to get blured when opening the dropdown. the stacktrace is:
q.closeDropDown (_HasDropDown.js.uncompressed.js:449) q._onBlur (_HasDropDown.js.uncompressed.js:304) u._setStack (focus.js.uncompressed.js:302) u._onTouchNode (focus.js.uncompressed.js:244) (anonymous function) (focus.js.uncompressed.js:114)
this is quite a critical bug for our application. any ideas for workarounds?

I was able to reproduce this, and fix it, at least in my tests.
When you mousedown on a HasDropDown subclass (like DropDownButton), HasDropDown sets up a mouseup listener at the document level. That listener listens for a single mouseup event and then removes itself. The problem is that we sometimes get two mousedown events in a row, causing us to lose the reference (this._docHandler) to that listener, so it never gets removed. Then when pressing button 1, button 2 reacts to the mouseup event.

I'll take a look, but which browser and OS is this happening on for you?
You might as well try 1.10 too; maybe I fixed this already.
