    Description

      All listeners should get invoked, even if they remove themselves while iterating the listeners. An index-based loop would skip the next listener in the list, and an iterator-based or range for loop ends up with invalid iterators unless it makes a (cheap) copy before iterating the listeners.

      The listeners were fixed in https://codereview.qt-project.org/#/c/159505/ but https://codereview.qt-project.org/#/c/155386/ reintroduced the issue for itemGeometryChanged().
