I don't think you intended to keep the typeof here?

No. Also there are other reasons why this doesn't work. Will look again.

With this PR, non-string
dangerousInnerHTML.__htmlis now handled during hydration the same way as we handle it during a pure client-only or server-only render.

You can see that the only ones that were failing are related to hydration. This tells us that the PR doesn't change the behavior for purely client-only or server-only renders, but it fixes the inconsistency when hydrating on top of good markup.
