This patch implements a simple <object> element with fallback content. If the URL from the data attribute fails to load (including 404), we render the DOM tree inside the <object> as fallback content. This works by generating a different layout tree for the <object> depending on the state and success of the data load. Since we cannot currently do incremental layout tree updates, we have to force a complete layout tree rebuild when the resource load finishes/fails.
