Automatic update from web-platform-tests De-flake moving-between-documents WPTs The moving-between-documents tests were flakily timing out with: "TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'." This occurred because the helper script's createDocument resolved the promise as soon as it received the "fox" message from the iframe. However, the "fox" message is sent from the iframe's <head> before the <body> (which contains the <streaming-element>) is parsed. If the iframe parser yielded, the parent would query for <streaming-element> before it was parsed, returning null and causing appendChild to fail. This CL fixes the issue by using a MutationObserver in the helper's createDocument function. If inlineOrExternal indicates that a <streaming-element> is expected, we wait for it to be added to the DOM before resolving the promise.
