Apparently the checking for style sheet response headers isn't as strict as I was led to believe. It seems that if there's no / or \ in the response Content-Type it is simply ignored and the style sheet is applied. This seems like a bug.
A comparison against "UNKNOWN_CONTENT_TYPE" was added in bug 177026, which seems likely to have caused this (original implementation of this behavior was in bug 46225).

Please let me know the outcome of fixing this bug so that I can determine whether or not to change the HTML5 spec. Thanks!
The HTTP implementation in necko treats a Content-Type header that does not parse as a valid content type as equivalent to a non-existent Content-Type header. The CSS loader assumes that things without a Content-Type header are CSS, which I think is what we want it to be doing. So there's definitely no style system bug here. I would say there is no Necko bug either.
