QtQuick problem with synthesized mouse events from stylus events

Running the qtdoc/examples/demos/dice example. There are two problems when running on chrome/webassembly.

What is strange, and possibly a bug in chrome, is that the mouse events are reported as stylus events.

Problem 1) Click/release on the round menu button does not work
(click/wait/release does work)

  The problem here might be that setPressed(false) is called twice, the first time from QQuickItem::forceActiveFocus() as the release of the stylus is detected
(menubutton.log is  attached)

Problem 2)
  If rotating the view, it is not possible to drop the dices on left mouse click

MousePress ->
 ApplicationWindow ->
   QQuickOverlay
   QQuickMouseArea
   QQuick3DViewport

MouseRelease ->
  ApplicationWindow ->
    QQuickWindow

(Attached press-release.log)
