Automatic update from web-platform-tests Don't propagate frameset CSS properties to the viewport (#28660) Document::body() will return the <frameset> element for documents where a frameset is found before body and the frameset is rendered. Do not propagate any properties from the frameset for viewport propagation as the specifications[1][2][3] explicitly talks about the body element.
