So, what's interesting about this to me is that
a) Adam Barth's current mime-sniff draft [1] rules it out (because
text/plain to text/html is classified as privilege escalation,
because text/html is 'scriptable');
b) The _reason_ it is ruled out has nothing to do with the problem
you are pointing to!
That is, supposing there were a media type text/staticHTML, which
meant, effectively, interpret as HTML with noscript applying
throughout. Barth would not classify text/plain -> text/staticHTML as
privilege escalation, so it would be allowed, and _then_ the problem
your example illustrates would come into play . . .
