Reassigned/mutated module variable not marked as such

[Conduitry]

<script context='module'>
  let foo = {};
  let bar = {};
  foo = 1;
  bar.x = 1;
</script>

<script>
  foo = 2;
  bar.x = 2;
</script>

results in a vars value of

[
  {
    name: 'foo',
    export_name: null,
    injected: false,
    module: true,
    mutated: false,
    reassigned: false,
    referenced: false,
    writable: true
  },
  {
    name: 'bar',
    export_name: null,
    injected: false,
    module: true,
    mutated: false,
    reassigned: false,
    referenced: false,
    writable: true
  }
