Issue: #8297

What I did

How to test

1. add .addDecorator(withStorySource('test')) to stories, or:

   addons.getChannel().emit('storybook/source-loader/set', { edition: { source: 'source' }, location: {currentLocation: undefined, locationsMap: {}} });

2. add the following to the .storybook/webpack.config.js file:

   { loader: require.resolve('@storybook/source-loader'), options: { injectDecorator: false } }

Then the code should be loaded successfully in the "Story" Panel. if the Injector is not disabled, the stories decorator code is overwritten by the loader.

@LeeBurton we recently overhauled source-loader and addon-storysource as part of 6.0. if you have time, please give them a try.
