Svelte dynamic multiple attribute on two-way binding of select does not work

App.html

<h2>Static multiple attribute</h2>
<select bind:value="works" multiple :size>
	{{#each options as option}}
	<option value="{{ option }}">{{ option }}</option>
	{{/each}}
</select>

<h2>Dynamic :multiple attribute ({{ multiple }})</h2>
<select bind:value="broken" :multiple :size>
	{{#each options as option}}
	<option value="{{ option }}">{{ option }}</option>
	{{/each}}
</select>

<script>
	export default {
		data() {
			return {
				works: [],
				broken: [],
				options: [ 'foo', 'bar', 'baz', 'qux' ],
				multiple: true,
			};
		},
	};
</script>

data.json

{
  "works": [
    "foo",
    "baz"
  ],
  "broken": [
    "qux",
    "bar"
  ]
}
