Frame targets' lifetime is bound to the WebFrameProxy. During a cross-origin page navigation, as much of the page's structure will be preserved alongside the WebFrameProxies, and they merely get assigned new web processes rather than being destroyed and recreated with the new page. This means we need to recreate them as frame targets after the navigation clears out all sub targets in the web page as we can't rely on the new WebFrameProxy code path rdar://172326572
