+<!--
+
+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.
