    Description

      I'm trying to track the hovered state of some items inside of ListView.

      The problem is that both MouseArea.containsMouse and HoverHandler.hovered can be set to true even if mouse cursor is not located above them anymore.

      I've attached minimal reproducible samples for both controls, and also video. The bug behaves differently under different OSes and for different controls. Inside of our real application it behaves even worse than in this minimal reproducible sample application.
