[Typo]: editing `serverUrl` in the sandbox as directed does not cause the Effect to re-synchronize

Summary

These two sentences at https://react.dev/learn/lifecycle-of-reactive-effects#how-react-verifies-that-your-effect-can-re-synchronize don't make sense for the given example.

For example, try editing the serverUrl in the sandbox above while the chat is open. Notice how the Effect re-synchronizes in response to your edits to the code.

Details

In that sandbox example, serverUrl is not a reactive value.

Editing its value in the sandbox does not cause the Effect to re-synchronize.

Was the intent to demonstrate Fast Refresh (React's hot-reloading)? If so, it doesn't seem to work in the Sandpack environment. Editing the serverUrl value in the Sandpack sandbox does not cause the Effect to re-synchronize.
