Ok, I think this is problematic due to the accessibility set up. We rely on the CachedImage object to retrieve the corresponding AccessibilitySVGRoot when detaching. But since that's been cleared, the detaching was fail so that the AccessibilitySVGRoot object is still pointing to the RenderImage's ax render object as parent.
