Debugging Ionic 2

Good morning,

I am playing with Ionic 2 and was trying to debug using map files.
I enable map generation in the web pack config file (devtool: ‘source-map’), but I was surprised it was not working on Safari.

Not sure why but looks like Safari (work using Chrome) stop loading map files when it found a missing one.

Does any one knows a way to add all missing map files (es6-shim.map, …)?
Or clean all # sourceMappingURL in the app.bundle.js except the app.bundle.js.map ?

Thanks,
