Svelte 5: Parse error in comment in template interpolation

[ota-meshi]

Describe the bug

he following code seems to result in a parsing error when using svelte 5.0.0-next.190.
However, if I remove the comments the parsing works fine.

<script>
function foo () {
	return "42"
}
</script>
{foo(/*comment*/)}

Severity

blocking an upgrade

From what I've checked, using 5.0.0-next.184 seems to be fine, but I think the same problem will occur with 5.0.0-next.185.
