Summary: Fix support for `useRecoilSnapshot()` when Fast Refresh. (Note this is dev-only) React's "Fast Refresh" will detect changes to source and re-load and re-render components with the new implementation. However, it appears to call the new render, then the previous effects cleanup handler, then the new effects. This seems strange and caused the snapshot to be released before the new effect retained it. Don't expect behviour change from React, so workaround is to defer the release with `setTimeout()` so the new effect after the fast refresh has a chance to retain it before the old effect cleanup releases it.
