Missing autocomplete suggestions for namespaced components in the template

[AdrianGonz97]

Describe the bug

If we were to reexport components like so:

import Button from "./CardButton.svelte";
import Title from "./CardTitle.svelte";
import Description from "./CardDescription.svelte";

export default {
	Button,
	Title,
	Description,
};

and import them to be used as a namespace:

<script lang="ts">
	import Card from "./Card.svelte";
	import C from "./children";
</script>

<Card>
	<C.Title>Hello World</C.Title>
	<C.Description>
		Lorem Ipsum is simply dummy text of the printing and typesetting industry.
	</C.Description>
	<C.Button>Get started</C.Button>
</Card>

---

Then we wouldn't get any autocomplete suggestions when typing <C.>...

---

But! If we were to close the suggestions and reopen it again (so long as we have some valid starting letter), then we'd actually get the proper autocomplete suggestions.

Reproduction

git repo:

git clone https://github.com/AdrianGonz97/no-autocomplete-suggestions-on-namespaces-issue

Expected behaviour

Ideally, the provided suggestions would be the same as if we were to place the value in mustache tags, like so:

System Info

• OS: WSL2 Ubuntu
• IDE: VSCode

Which package is the issue about?

Svelte for VS Code extension, svelte-language-server

Additional Information, eg. Screenshots

Closing as duplicate of #776. This is a limitation we have now. If the template has a syntax error, only global completion will be shown. We have special treatment for mustaches, but the same technique is not applicable in a namespaced component.

@jasonlyu123 Thanks for the quick response, it's very much appreciated!

Might I make a suggestion about editing the title of that original issue to include "Namespace"? It would probably make it easier for people in the future that want to search for that issue 😄
