[Qt-qml] How to reset MouseArea onEntered/onExited status?

[light frank]

I move the MouseArea out of the rectangle, the mouse event can be received
both when the rectangle is visible or invisible, I think this is unexpected.
If I disable the mouse area when the rectangle is invisible, it's behavior
will be the same as the original code.
Another question is, if I want to encapsulate the rectangle/item and it's
mouse area into one widget, how can I achieve this, i.e. the widget is
invisible and it's mouse area is active?
Thanks.
