storybook: Storybook server does not start if error in initial build, even after fixing

Describe the bug The Storybook server running on localhost:6006 does not start if you startup storybook with initial errors in your JS. Even after fixing, the server never manages to start so you have to kill and restart Storybook.

To Reproduce Steps to reproduce the behavior:

1. Start storybook with some JS error in your Story source/imported JS
2. Storybook fails to start (expected)
3. Fix error
4. Storybook build starts but server never starts up (eg localhost:6006 is not running)
5. Have to kill and restart storybook for it to work

Expected behavior Server to start after initial error is fixed.

Additional context Should be repeatable with a brand new build of Storybook. I’m using React but I assume it is a general problem? Not using CRA
