Can not compile complex {#if}

[Kauto]

While using a complex {#if} statement, svelte is compiling to invalid javascript.

<script>
	let item = {
		divider: [1],
		sub: {
			first: '/first',
			second: '/2',
			third: '/3'
	  }
	}
</script>

{#each Object.entries(item.sub) as [subName, path], i}
{#if (item.divider && item.divider.includes(i))}
<div class="divider"></div>
{/if}
<a href="{path}">{subName}</a>
{/each}

Module parse failed: Unexpected token (285:7)

To Reproduce
Look at the code produced in this REPL:
https://svelte.dev/repl/8a129823894a48cb944245fb7bc1d6fe?version=3.9.1

you can see the error in the JS-output in line 71.

Expected behavior
Code compiles.

Severity
It was working in old versions, so now I have to downgrade.

Yep, thanks. This worked in 3.9.0. Presumably caused by #3438.

Fixed in 3.9.2! thanks
