--- Comment #3 from roberto.vidal at ikumene.com ---
This is well above my paygrade, but from what I can gather, the issue lies here: https://github.com/WebKit/WebKit/blob/729daab8b1fcb955d6e487a7b6266894695972f5/Source/WebKit/NetworkProcess/NetworkResourceLoader.cpp#L666

When `shouldInterruptNavigationForCrossOriginEmbedderPolicy` is called, the `m_response` is _not_ yet updated in the case of a cache hit, but it is instead set to a dummy value (presumably the empty URL set in https://github.com/WebKit/WebKit/blob/729daab8b1fcb955d6e487a7b6266894695972f5/Source/WebCore/loader/FrameLoader.cpp#L382 ?).
