The problem is that when the main resource is loaded from the memory cache, the callback assignIdentifierToInitialRequest() is not called, so from the API point of view the main resource load never starts. 

This happens because when the main resource is loaded from the memory cache the response is not added to the ResponseVector of the document loader, so that when committing the provisional load the remaining delegate messages are not called because the ResponseVector of the document loader is empty. When the main resource is loaded from the memory cache, there's no resource loader, and the client is notified about the response using ResourceLoadNotifier::dispatchDidReceiveResponse() directly instead of ResourceLoadNotifier::didReceiveResponse() which is the one adding the response to the ResponseVector of the document loader. So, the problem can be fixed by adding the response to the ResponseVector before calling dispatchDidReceiveResponse() when loading the main resource without a resource loader.

Reassigning to Page Loading since this is a regression in the WebCore loader.
