| <!-- |
| Compare this to cross-document-traversal-cross-document-traversal.html. Since |
| there are no network loads or document unloads to cancel tasks, both |
| traversals should observably go through. Target step calculation for the |
| second traversal should take place after the first traversal is finished. So |
| we end up with both traversals observable in sequence. |
