TapHandler sees Stylus events that should be handled by items on top

If I have a TapHandler with a popup Menu on top, or a MouseArea on top, stylus taps are sometimes handled by the TapHandler instead of the overlayed item. It appears to be non-deterministic when the TapHandler will interfere with other items. This only happens with a stylus, not with a mouse or touch. The behavior seems the same on both Windows and Android. Have a play with the attached QML code and you should be able to get TapHandler events when you select a menu item or tap in the blue MouseArea.
