Learning: The useGlobals hook from storybook/manager-api returns a tuple where the third element (storyGlobals) is typed as Globals, not Globals | undefined. This means TypeScript guarantees it's always defined, making the `in` operator safe to use without additional null checks.

25-32: Timeout + logging behavior is solid; consider extracting the timeout constant.The 5s
AbortSignal.timeout(5000)on the Storybook health-check fetch and the verbose catch block that logs the URL plus error both look correct and solve the hanging issue without changing the success/false semantics.If you want to make future tuning easier, you could pull
5000into a named constant (e.g.,const STORYBOOK_HEALTHCHECK_TIMEOUT_MS = 5000;) near the top of the file or next tocheckStorybookRunning, but this is purely optional.

Learning: When reviewing async functions that perform side effects like opening browsers, `.catch()` is preferred over `await` if the operation should be non-blocking. This prevents unhandled Promise rejections while keeping the operation as fire-and-forget.

Hi, are any more actions required for this? |
Closes #
What I did
Added a timeout for the fetch request in global setup, and log when this request times out. This fixes a problem I encountered where if a process on port 6006 is listening to the request but not responding then the request will hang until the fetch request itself times out after some longer duration of time (this time was 5 mins when i encountered it) which was very confusing and difficult to track down the root cause to.
