https://html.spec.whatwg.org/multipage/webappapis.html#event-loop-processing-model implies that once you've collected the set of documents in step 11.1, you use that same set for all the subsequent steps. We don't follow this; we call forEachDocument() at each step, so potentially we'll pick up a new document that was added by the previous step.

Right, I wanna make this code change with a test.
