For the record, in the context of the WHATWG mailing list, saying "work"
here is fine. What's important is the user experience, not strict
adherence to specifications.
In the case of the HTML spec, I'll change it to match what user agents
implement. As mentioned earlier in the thread, for now I'm happy to "give
cover" to Firefox and Opera (and hopefully Chrome and Safari) to more
closely honour the Content-Type headers, but if the conclusion from
implementors is that following Microsoft's route towards simply ignoring
Content-Type with <video> as we do with <img>, that's fine.
As far as sniffing for top-level browsing contexts goes, my understanding
is that Adam is still working on the relevant spec, and it would not be a
problem to add common video formats to that algorithm so that we can get
interoperable handling of mislabeled content.
(Currently, text/html won't ever sniff as binary IIRC, but text/plain, in
certain cases, will. We could also make text/html sniff as binary if it
turns out that this would be particularly helpful for Web compat.)
