Is History API broken on iOS? (Location bar doesn't update on pushState)

Filing this under the either the I Can't Believe No One Noticed This Before or the I Must Be Missing Something categories:

It appears that if you do a simple window.history.pushState on iOS, the location bar doesn't update unless it is in response to a user gesture. The state itself does get pushed (as you can see by hitting the back button button).

Here's is the tiniest test-case I could come up with recreate the issue:

On a desktop browser that supports the History API, you should see the URL in the location bar change to /0, /1, etc., every second. On iOS – tested with iPhone (running iOS 4.3) and iPad (running iOS 4.3.3) – the location bar doesn't update but hitting the back button will take you the correct previous location (which will 404 on the test-case since there's no back-end logic to handle those URLs).

Thoughts? Workarounds? A shoulder to cry on and hugs?

UPDATE: this issue was fixed in iOS 5.
