System Info

No response

Any additional comments?

It works with vue@2.6.11 https://codesandbox.io/s/objective-flower-3o5h2o?file=/src/App.vue

Because the style was scoped, what happened is that the extends options allowed the reuse of template markup only.

It is June 2023, Vue version 3.3.4 and the issue is still not resolved nor commented. @yyx990803 I know, that this feature was not officially documented, but it was working in Vue 2.x version. Could you please share your thought on that?
