Type casting inside reactive blocks causes errors

[bennymi]

Describe the bug

Adding type casting inside a reactive block causes an error. This worked in Svelte 4.

<script lang="ts">

    let anchorEls: HTMLAnchorElement[] = [];

    $: {
        anchorEls = <HTMLAnchorElement[]>Array.from(document.querySelectorAll('a'));
    }
</script>

<a href="#1">1</a>
<a href="#2">2</a>

simpler reproduction. Seems the cast is treated as JSX, wondering if there's an option in the Acorn TS plugin to not do that. Either way, it's best to use as type casts instead, i.e. do

    $: {
        anchorEls = Array.from(document.querySelectorAll('a')) as HTMLAnchorElement[];
    }

instead
