Event handlers types not working properly in <svelte:element> unless a prop is explicitly specified

[alialaa]

Describe the bug

I am creating a Button component where it can be an html button element or an anchor tag based on whether an href prop is passed or not. I am typing my props like so:

It seems to be working fine except when using an event handler, I get this error: Parameter 'e' implicitly has an 'any' type.

However when explicitly setting href to undefined it works fine:

Reproduction

I believe everything is provided in the screenshots but here's the code as text:

<script lang="ts">
	import type { Snippet } from 'svelte';
	import type { HTMLAnchorAttributes, HTMLButtonAttributes } from 'svelte/elements';

	type Props = (
		| (HTMLButtonAttributes & { href?: never })
		| (HTMLAnchorAttributes & { href: string })
	) & {
		children: Snippet;
	};

	let { children, ...props }: Props = $props();
</script>

<svelte:element this={props.href ? 'a' : 'button'} class="button" {...props}>
	{@render children()}
</svelte:element>

Expected behaviour

I expect that passing href={undefined} should not be required.
