Thanks, http://html5.org/tools/web-apps-tracker?from=5376&to=5377
looks good to me.

This seems related to the thread from around a month ago when I asked
about setting location.href before onload (Gecko, and now WebKit, will
not create a new session history entry if this happens before load).
Throwing an exception, ignoring the pushState, or having it be treated
as replaceState all make sense to me.

At least a note that the pending state object is not affected by
push/replaceState makes sense.
