What is the issue with the HTML Standard?

https://html.spec.whatwg.org/multipage/browsing-the-web.html#scroll-to-fragid

After firing the navigate event in step 4, the spec indicates that if it was not intercepted, then the popstate event gets fired through the "Update document for history step application" in step 14.

But if someone did intercept the event, then the state update gets handled by the navigation API's commit behavior which is explicitly not done in https://html.spec.whatwg.org/multipage/browsing-the-web.html#url-and-history-update-steps (the steps intercept uses to update the URL).
