QML: ScrollView and MouseAreas: 'mouse hover' not detected on the scrollbar - hover

Question

I have a QML application and need to open a dialog when I press a button. The dialog must be closed when the mouse is out of the dialog (with no click, so I think 'Popup' control can not be used).
For that, I use MouseAreas and control when the mouse is over one of my MouseAreas. I solved some problems (see QML: Problems with mousearea overlapping), but now I found another problem with a ScrollView (the dialog must contain a ScrollView with a ListView). I can not control when the mouse is over the scrollbar... And the dialog is closed since no MouseArea "has" the mouse over...
How can I control the mouse events on the scrollbar?
Thanks in advance,
Diego
