I’ve got a repro for this over on #21402: https://github.com/web-reprex/prettier-list-different

When I run this project, I see an error in DevTools:

Error: Cannot remove node “25” because no matching node was found in the Store.

This is very promising!

Looks like there’s a problem with Suspense and LegacyHidden.
