Describe the bug

In runes mode, when iterating an array of objects in an each loop, it is not possible to bind the object to a component.

<svelte:options runes={true} />
<script>
	import Component from "./Component.svelte"
	
	let objs = [{
		val: "foo"
	}]
</script>

{#each objs as obj}
  <Component bind:obj />
{/each}

Error each_item_invalid_assignment is raised. This works fine when runes mode is disabled.

Logs

Cannot reassign or bind to each block argument in runes mode. Use the array and index variables instead (e.g. `array[i] = value` instead of `entry = value`)
