Allow <iframe src="javascript:''"> to commit synchronously. made all javascript url navigations async.
Some sites appear to depend on "javascript:''" behaving like
"about:blank" and committing synchronously.

The spec doesn't say anything about this, but given the real-world
breakage, I'm inclined to consider this a very narrow partial revert
of while we figure out whether this is a spec
oversight or a case where we just need to encourage libraries to update.
