Say I have two loaders:

• react-hot-loader, a pitch loader (internally using a transforming loader, but that doesn't seem to change things, as I've got similar problems with bundle-loader which is purely pitch loader)
• jsx-loader, a transforming loader

If I use just jsx-loader, filenames are preserved:

{ test: /\.jsx$/, loader: 'jsx' }

If I chain loaders, the filename corresponds to the "outer" pitching loader, and not to the source file:

{ test: /\.jsx$/, loader: 'react-hot!jsx' }

The original file (before the pitch) gets a long name, and devtools just call it jsx-loader in title which is highly inconvenient:

From my understanding, adding source maps won't help because the issue isn't in transforming code, but in resulting filenames.
