DropDownList in a Callout(Button) closes the Callout after selecting an item in the DropDownList

Hi

A DropDownList in a Callout(Button) calloutContent closes the Callout after
selecting an item in the DropDownList...
(using SDK4.11 in a web application - testing with FlashDebugPlayer 11.9)

This happens because the DropDownManager adds mouseDown triggers to the
systemManager which than closes the callout as well when the DropdownList
closes

The only workaround I found to prevent this is to get a reference to the
systemManager in my view which uses the Callout and override the
MouseEvent.MOUSE_DOWN and SandboxMouseEvent.MOUSE_DOWN_SOMEWHERE and
stopImmediatePropagation() there..

this works, i can select an item without the Callout gets closed but the
downside is that the Callout stays open when i click somewhere outside the
calloutContent what normally would close it.
Re-clicking the calloutButton closes the Callout though..

But anyways, i find this solution not optimal because override the
systemMangers mouseDown and stopImmediatePropagation() there could have
other influences on other components in the view and i would have to check
with a flag if the Callout is actually open etc...

So my question is if anyone sees another workaround for this problem or if
this could be considered as a bug?
