    Resolution Note (2021.2.X):

    In the version it was introduced the click target object became its own cached object. The CanvasGroup.blockraycast doesnt prevent the system from bubbling up the event to its parent (otherwise clicking on text or regular image on a button wouldn't work). In this case the need to inherit OnPointClick (the same way OnPointerDown is used) is required to capture the event (the CanvasGroup is doing nothing in this example).
