If the UI_AnimateMenu effect is enabled, events are not passed to the menu until its animation effect has finished. Thus, if a context menu is invoked over a valid index in a QListView, the list view's clicked() signal will be emitted if the mouse button is released before the context menu's animation effect has finished. The clicked() signal is not emitted if the UI_AnimateMenu effect is disabled.

The clicked() signal should not be emitted if the mouse button is released before the context menu's animation effect has finished.
