Describe the Bug

Using the same reproduction as #12702, following the fix in #12715, HMR is triggered several times upon a single change.

It appears that some reloads are too early, as they will show the old content, and only the later reload will show the new content.

In the below video, the final edit takes ~30 seconds per reload but the first reload shows the same content as before.

What's the expected result?

Only a single reload happens, with the updated content.
