QDrag and hover of widgets at the end, possible issue of QT

Hi,
When you do a QDrag and during the drag you go on a QLineEdit for example and then drop outside it, at the end the hover color is there.
The user must go on the widget with the mouse to remove the hover color.
Is it an issue of Qt ? If yes, I will add a ticket.
Thanks
