The only hint I found on the web is this

Any idea? Thanks.

Can't you use webessentials / some tools or a grunt task to transform your less file and only include the css in your StyleBundle ? — christophe.chapron, Sep 26 '15 at 13:34
I'd say do the bundling before deploying with something like gulp. It's the vNext way to do it anyway — MikeSW, Sep 26 '15 at 13:35
I already did the "trick" with webessential but it's to bad it didn't work with the right way. :-s — Cantinos, Sep 27 '15 at 13:09

Most likely, on the server is installed an old version of the Internet Explorer (before version 9.0), which does not support the Chakra JavaScript engine.
