Currently, if the main frame navigates to a site that is already loaded in a child frame, ProvisionalPageProxy reuses the remote page’s message receiver and page identifier. This cannot work when we need to cache the iframe’s page that is being navigated away from. Reusing the message receiver and page’s main frame is only necessary when a new window is opened, so we should restrict this behavior to that case.
