Once we paint, it's way too late for this check to happen anyway. Additionally, the spec's steps for retrieving the content document assume that both the browsing context's active document and the container's node document are non-null, which evidently isn't always the case here, as seen by crashes on the SerenityOS 2nd and 3rd birthday pages (I'm not sure about the details though). Fixes #12565.
