ComboBox: Don’t popdown if releasing on scrollbar

Browse Source 
On button release, we were popping down if the event widget was anything
but priv->button. This broke scrolling by clicking a mouse button, i.e.
when releasing a click in the trough or finishing a drag of either bar.
That’s unexpected, inconvenient, and pointless. So, let’s stop doing it.
