I don't understand how that works.  The answer is buried somewhere in the
closed-source CFNetwork.  Maciej hinted that it had to do with the file
extension, but I couldn't verify that.

It shouldn't change that behavior, as far as I know.  If CFNetwork is somehow
magically sniffing text/css from text/plain, that violates the HTML 5 spec and
is inconsistent with Firefox's behavior.

> Also, wouldn't a regression test for this change be helpful?

I could add a test, but it won't appear to be any different since we're not
changing the CFNetwork behavior.  I'll add a test on the Chromium side, where
we will see a difference.
