Research direction
Investigate the source code of @storybook/experimental addon test, specifically how it configures Vite. Look for any Vite config that might need to polyfill node:process or set appropriate resolve conditions. Check if there is a similar issue in the Storybook repo or Vite documentation for handling node modules in browser context. Consider adding a Vite plugin or adjusting the addon's configuration to handle node:process correctly.
