hack adapted from #21061 to enhance history.pushState

openapi-explorer uses pushState with anchor only, but this doesn't work
with base tag, as anchor is added to the base url instead of current
url. So override the replaceState function to construct the full url
based on current location

Probably not needed very soon, as
Authress-Engineering/openapi-explorer#292 was quickly merged
