Fix dec7ff6b0c: Dropdowns couldn't be closed by pressing the parent button. (#10954)

Browse Source 
Since dropdowns self-close, the detection of re-clicking a dropdown
button no longer worked, as the dropdown is already closed.

Instead set (and then test) a flag on the parent widget to indicate that
the dropdown closed. This method avoids looping windows on every click.
