Svelte component not rendering its children

[codectl]

Describe the bug

There appears to be an error when rendering a component containing children when using the newly introduced {@render children()}

let {children} = $props()

<Button
  on:click
  on:keydown
>
  {@render children()}
</Button>

The error on the parent is Svelte: Type () => any is not assignable to type never.

Reproduction

let {children} = $props()

<Button
  on:click
  on:keydown
>
  {@render children()}
</Button>

Expected behaviour

No errors

Is the Button component from a library? If so, this might be because the component library provides type definition with Svelte 4 slots and We might need to find a way to map that into svelte 5 snippet.

We need a more complete reproduction, this is enough to reproduce this

This is spot on.
