Modal closes when suspended and closeTimeoutMS is set

[tstehr]

Summary

When a ReactModal is inside a Suspense component in React 18 and closeTimeoutMS is set, the modal will close when suspended, and not reopen afterwards, even if isOpen is still true.

Expected behavior

1. The modal is shown
2. It then vanishes briefly while a "Loading" text is visible. The loading text is the fallback of the Suspense component, which is shown because a component is loaded in lazily.
3. It's then shown again as soon as it is unsuspended.

Actual behavior

1. The modal is shown
2. It then vanishes while a "Loading" text is visible.
3. It stays closed even after the load is finished and the other components in the Suspense unsuspend
