Chrome white flash in dark mode

I really can't blame Google for not having readily accessible support staff or communication channels when odds are that 99% of incoming issues will read just like this thread: abrasive, presumptuous, entitled, and just plain rude.

Not to mention unhelpful and among the 30 of them unable to post reproduction steps - I've given it an honest think and I'm still confused what they're talking about. That a page is white on refresh/navigation before content renders?
