This patch implements the "create a new browsing context" function from the HTML spec and replaces our existing logic with it. The big difference is that browsing contexts now initially navigate to "about:blank" instead of starting out in a strange "empty" state. This makes it possible for websites to create a new iframe and start scripting inside it right away, without having to load an URL into it.
