ReferenceError when using RequireJS

[jjoekoullas]

source-map-support doesn't install a global when using RequireJS - this causes client.js to throw a ReferenceError: sourceMapSupport is not defined.

I have the same issue.

Temporary workaround using patch-package:
patches/karma-source-map-support+1.4.0.patch
