[Bug]: addon-storysource doesn't display the full source

Describe the bug

I am using storybook react of version v8.3.6 . I have added storysource addon to the react webpack storybook sample in stackblitz to test the display of story file's full source in the addons. I am not able to bring it up. It only brings up the 'code' tab in the addons and displays the rendered piece of code for that particular story

Please find my main.js file below

/** @type { import('@storybook/react-webpack5').StorybookConfig } */ const config = { stories: ["../src/**/*.mdx", "../src/**/*.stories.@(js|jsx|mjs|ts|tsx)"], addons: [ "@storybook/addon-webpack5-compiler-swc", "@storybook/addon-onboarding", "@storybook/addon-links", "@storybook/addon-essentials", "@chromatic-com/storybook", "@storybook/addon-interactions", "@storybook/addon-storysource", ], framework: { name: "@storybook/react-webpack5", options: {}, }, }; export default config;

Reproduction steps

In the stackblitz link , please note the addon-storysource being added to main.ts file's addons
Though the code tab appears in the addons section, it doesn't display the story's source in it
