Bind to component instance - types missing in runes mode

[sbmw]

Describe the bug

Typescript types don't seem to be generated for use when binding a component instance via bind:this - but only when the bound component is in runes mode.

Edit to add: this is a tooling issue only. The component instance binding and use of exported functions works great in both cases.

Reproduction

Simple repro here - https://github.com/sbmw/bind-component - but details also listed below for ease.

Create two components, exporting a function. Use runes in one.

<script lang="ts">
	export function saySimpleComponent() {
		alert('Simple Component');
	}
</script>

<script lang="ts">
	let message = $state('Runes Mode Component');
	export function sayRunesModeComponent() {
		alert(message);
	}
</script>

Import and bind to the components from a parent component/page.

<script lang="ts">
        import SimpleComponent from '$lib/Simple.svelte';
	import RunesModeComponent from '$lib/RunesMode.svelte';
	let simpleComponent: SimpleComponent;
	let runesModeComponent: RunesModeComponent;
</script>
<SimpleComponent bind:this={simpleComponent}></SimpleComponent>
<RunesModeComponent bind:this={runesModeComponent}></RunesModeComponent>
<button
	onclick={() => {
		simpleComponent.saySimpleComponent();
	}}>Simple Component</button
>
<button
	onclick={() => {
		runesModeComponent.sayRunesModeComponent();
	}}>Runes Mode Component</button
>

Result:

SimpleComponent is identified as a SvelteComponent type, providing intellisense etc.

let runesModeComponent: RunesModeComponent throws "'RunesModeComponent' refers to a value, but is being used as a type here. Did you mean 'typeof RunesModeComponent'? ts(2749)". No intellisense for the exports on runesModeComponent.

Ahhhh - I thought it hadn't been throwing this TS error previously. This is the issue I was looking for: sveltejs/language-tools#2522
