[SafeEval]

Please provide us with the following information:

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)

Linux

1. Versions. Please run ng --version. If there's nothing outputted, please run
   in a Terminal: node --version and paste the result here:

angular-cli: 1.0.0-beta.15
node: 6.2.2
os: linux x64

1. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.

This is a basic default application, generated and built with the angular-cli. Following the defaults, the resulting build is stored in dist/.

ng new myproject
ng build

1. The log given by the failure. Normally this include a stack trace and some
   more information.

N/A

1. Mention any other details that might be useful.

The generated dist/index.html file contains the following line:

<script type="text/javascript" src="inline.js"></script><script type="text/javascript" src="styles.bundle.js"></script><script type="text/javascript" src="main.bundle.js"></script></body>

RFC 4329 Secion 7.1 says that the MIME type "text/javascript" is considered obsolete, in favor of "application/javascript".

That code is autogenerated by Webpack when building the project. This issue is better suited on that repo instead: https://github.com/webpack/webpack
