[QML] Dragging/Flicking in Flickable keeps "pressed" to true in child MouseArea

Expected results:
When using a Flickable that has a MouseArea inside it, activating the drag functionality of the Flickable should set "pressed" from MouseArea to "false".

Actual results:

Using a Flickable's drag while a MouseArea rests inside turns the "pressed" property to "true" and does not return to false, even after the mouse press has been released, unless user double-clicks or minimizes the window and reopens it. Emitting "released", "canceled" or even "clicked" and "doubleClicked" does not fix this problem.
