This causes undesirable nondeterminism, as if you change a page's fragment before the load event, sometimes you will get events in the order [popstate, hashchange], and sometimes [hashchange, popstate], depending on how long it takes for the page to load. Firefox has a simpler model of always firing popstate synchronously. We are speccing that in https://github.com/whatwg/html/pull/7815 and Chromium will be working to align in https://bugs.chromium.org/p/chromium/issues/detail?id=1254926 / https://chromium-review.googlesource.com/c/chromium/src/+/3580022 . (Note that the current spec, before that spec PR, matched no browser.)
