Fix accidental selection of popup items under the mouse in QComboBox
Fix accidental selection of popup items under the mouse in QComboBox

If the widget under mouse is hidden, Qt can generate a synthetic mouse move
event which gets delivered to the already hidden widget. This can then result
in the wrong item being selected.

Workaround: in QListView, ignore mouse move events when the widget is hidden.
