Was this related to HMR as well? I wonder how a shadow root is already attached 🤔

Yes that was the only fix required for HMR to work without issue. It was in the case that a component is mounted, HMR reloads with that component no longer mounted, then HMR reloads a 2nd time with it mounted once again. Reproduction details are in #38

Thanks for fix! Will try in my app as well upd: oh, looks like they updated something else and we need another PR |

This fixes the 2 broken issues from #38
The Trend issue is due to preact rendering the component with serialized parts, so implementing the same fix for React19 will work. Even though preact is using React18 under the hood, it supports custom elements differently.

Unfortunately I can't find a way to tell if
preactis in use. It might be necessary to provide another export@number-flow/preact, or add a prop, or rely on an env variable to change the behaviour
