docs wrongly say that in script setup components are automatically registered locally when they are not

[jacekkarczmarczyk]

Docs

https://vuejs.org/guide/components/registration.html#local-registration

When using SFC with <script setup>, imported components are automatically registered locally:

If they are registered locally it should be possible to do <component is="comp" />

Compiled JS

/* Analyzed bindings: {
  "Comp": "setup-const"
} */
import { openBlock as _openBlock, createBlock as _createBlock } from "vue"

import Comp from './Comp.vue';

const __sfc__ = {
  setup(__props) {

  
return (_ctx, _cache) => {
  return (_openBlock(), _createBlock(Comp))
}
}

}
__sfc__.__file = "App.vue"
export default __sfc__

@jacekkarczmarczyk I am not sure I follow 🤔 <component :is="Comp"></component> works for me on the playground

[jacekkarczmarczyk]

playground was mainly to show that the component is not being registered (in compiled JS)
(and that's why is="comp" doesn't work)

@NataliaTepluhina The problem is that a component can't be used via its string name with is. It isn't 'locally registered' in the same sense as it would be if it used the components: {} option. It isn't really being registered at all.

[leopiccionia]

Instead of stating that

imported components are automatically registered locally

that's false, because there's no registration in the generated code, docs should say something like

imported components can be locally used without registration

[skirtles-code]

@leopiccionia I like that approach. Did you want to create a PR for something along those lines? I can do it myself if not.

I'll open a PR tomorrow, thanks.
