auto backdropRenderer = renderer.backdropRenderer();
   ...
    renderer.setBackdropRenderer(*backdropRenderer);

don't we always end up either with no backdropRenderer or with one with the
correct parent (renderer)? I didn't look through all the cases but could you
explain the re-parenting case? (if no reparenting ever happens, we could make
this function a lot simpler)
