    Description

      If a touch is interrupted by setting a QQuickItem's visiblity to false, QQuickItem::touchEvent isn't called with a TouchCancelEvent like it should be.

      To reproduce:

      1. Build and run the attached example
      2. Touch and hold the on the right side, you should see events for TouchPointPressed and TouchPointMoved being logged.
      3. While still touching the right side, touch and hold on the left side to toggle the visibility of the other item.

      I would expect there to be a TouchPointCancel by now, but QQuickItem::touchEvent isn't called after the visibility is set to false.
