As reported in #3068
The problem is that the pass will properly create the Rotation or
Opacity item, but will not create the two way binding if there is no

change the rotation angle of the image, but not its parent Rotation
item.
Fix it by making sure there is always a binding.
Since the change only affect visual representation, I abused one of the
screenshot test to test this feature. And I also patched another bug
that some #[allow(unused_parens)] was not set in the 'init' callback and
would cause a warning in the test
