      Description

      PathView item does not appear in certain circumstance.

      Please see the attached example for more details. (main.qml)

       

      In this example, there is Repeater and PathView as contentItem in SwipeView.
      Issue occurs when Repeater generate items for the PathView in certain circumstance.
       

      How to repreduce:

      1. run the example
      2. click the remove button to remove model data in Repeater 
      3. click the add button to add model data 
      4. then, we cannot see the PathView Item
      5. after flicking the PathView, item appears.

       

      Just for the test, I modified as below and attached example works fine.
