Reproduction URL

I don't have a reproduction - (not sure where to begin with making one) - but I'm still filing a bug because I would assume this issue has been reported before and may have some simple explanation I'm missing?

Describe your issue

I add a tailwind class to my MDX doc or TSX. The class does not appear sometimes unless i close and restart storybook.

Meaning, i stop storybook, and completely restart the webpack process. Then the new classes are "seen"

Please consider providing a git repo that reproduces the unexpected behavior, so that we can troubleshoot the problem.

Going to convert this to a discussion since that was the intend based on the description:

If you have a reproduction and are certain this is an issue on the Tailwind side, feel free to re-open a bug report though!
