entity_metadata_wrapper does not load correct revisions

Latest dev of entity_api and field_collection.

I have a node containing a field collection, with revisions enabled.

function mymodule_node_view($node, &$view_mode, $langcode) {
  print 'NODE<br />';
  print 'vid: ' . $node->vid . '<br />';
  foreach ($node->field_field_collection[LANGUAGE_NONE] as $key => $collection) {
    print $collection['revision_id'] . '<br />';
  }
  
  print '<br />WRAPPER<br />';
  $wrapper = entity_metadata_wrapper('node', $node);
  print 'vid: ' . $wrapper->vid->value() . '<br />';
  foreach ($wrapper->field_field_collection as $key => $collection) {
    print $collection->revision_id->value() . '<br />';
  }

  die;
}

Output:

When viewing the latest node revision:

NODE
vid: 273
255
256
257

WRAPPER
vid: 273
255
256
257

When viewing an older node revision:

NODE
vid: 271
221
222
223

WRAPPER
vid: 271
255
256
257

entity_metadata_wrapper is loading the latest revisions for the field collection, not the field collection revisions specified by the wrapped node entity.
