It looks like this is related to the code in MainResourceLoader::willSendRequest.
There is a call to isPostOrRedirectAfterPost, and if that returns true, we force
the cache policy to ReloadIgnoringCacheData.  We then modify the ResourceRequest
of the DocumentLoader.

Subresources are impacted by this because FrameLoader::subresourceCachePolicy
inspects the ResourceRequest of the DocumentLoader.  As a result, all of the
subresources become conditional.

(This loader system is making my head explode.)
