    Don't clear hover state while a child dialog is open.
    
    Otherwise it won't stay open.
    
    Fixes regression from 7585f295363532eff51f7e11ef6b62925117aba4.
    
    The bug number referenced in the original change is invalid, but
    I don't think this should invalidate the intent of that fix. Kai
    please let me know the correct bug number so I can double-check.
