There is only 1 pre-render service per BrowserState which makes
the last created BVC the delegate for the the pre-render service
so when there are multiple windows, the last one created will provide
the webState to be replaced to the service and the service will use that
to get the navigation history which will be wrong in cases where the
prerendered webstate is not on the last created window.

As a work around pass the webstate to be replaced to the service
