coverage preprocessor kills sourcemaps

[haiko]

I have a setup in a typescript project where karma-coverage is used to get coverage for my typescript files. Only thing is that it disables to see the typescript files in the browser when I am debbugging.

The culprit is this statement in my karma.conf.js

preprocessors: { './lib/**/**.js': ['coverage'] },
