+A couple notes about the files scattered in this `resources/` directory:
+
+* The nested directory structure is necessary here so that relative URL resolution can be tested; we need different sub-paths for each document.
+
+* The semi-duplicate `window-to-open.html`s scattered throughout are present because Firefox, at least, does not fire `Window` `load` events for 404s, so we want to ensure that no matter which global is used, `window`'s `load` event is hit and our tests can proceed.

+
+This test tests the interaction of just two substeps of the "Update the
+rendering" steps in
+https://html.spec.whatwg.org/multipage/webappapis.html#update-the-rendering
+
+These are:
+
+ 1. Let docs be the list of Document objects associated with the event
+ loop in question, sorted arbitrarily except that the following
+ conditions must be met:
+
+ - Any Document B that is nested through a Document A must be listed
+ after A in the list.
+
+ - If there are two documents A and B whose browsing contexts are
+ both nested browsing contexts and their browsing context
+ containers are both elements in the same Document C, then the
+ order of A and B in the list must match the relative tree order of
+ their respective browsing context containers in C.
+
+ In the steps below that iterate over docs, each Document must be
+ processed in the order it is found in the list.
+
+and later:
+
+10. For each fully active Document in docs, run the animation frame
+ callbacks for that Document, passing in now as the timestamp.
+
+
+It tests this by setting up a tree of three documents, two children and
+one parent, and testing for the relative order of the animation frame
+callbacks for each.
