If you must get a separate popup notification, I'd rather you add a
-(void)popupChanged action to all comboboxes.

I'd prefer to not rebuild the entire layout whenever we clobber. Shouldn't this
only happen on language-triggered rebuild?

we talked about this and will wait until it's noticeable

Also, you presumably want to request a relayout here.

How could shouldClobber ever be true here? You're in the else-branch of the
first shouldClobber?
