When I set a CSS resource with template Processed CSS to be bypassed while developing Chrome refuses to load the stylesheet as stylesheet with the following error:

Resource interpreted as Stylesheet but transferred with MIME type text/html
Javascript files that are set to bypass also have Content-Type text/thml, but there the browsers do not complain.

I'm using Chrome Version 48.0.2564.116 (64-bit)

Please make sure that the resources have the correct Content Type in the response headers.
