Resource interpreted as Stylesheet but transferred with MIME type text/plain

[meinnamehier]

I am using Jenkins V 2.46.1

I can access the css files (e.g. https://raw.githubusercontent.com/afonsof/jenkins-material-theme/gh-pages/dist/material-green.css), put when I apply them using the Simple Theme Plugin, nothing changes.

When I use another theme, like this one, it works: http://jenkins-contrib-themes.github.io/jenkins-neo-theme/dist/neo-light.css

In the console output of Chrome I get this: Resource interpreted as Stylesheet but transferred with MIME type text/plain: "https://raw.githubusercontent.com/afonsof/jenkins-material-theme/gh-pages/dist/material-green.css".

Firefox even blocks this "malicious" request: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options

You can use rawgit to provide the correct MIME type https://cdn.rawgit.com/afonsof/jenkins-material-theme/gh-pages/dist/material-green.css
