entity identifier never set on views_bulk_operations_modify_action_form

Hello the community and the maintainers,
Hope there is no other related issue, though I searched a bit already ;-)
I encountered an issue while using vbo with workflow on a field collection (not sure it is related to the field collection thing anyway...), to modify the entity value on the workflow field. It appears the transitions were not displayed the way they were supposed to. I fist though about a workflow-related issue. But, digging further the issue, it appears transitions were not retrieved because the entity id of the field collection were never set correctly on this specific instruction, on actions/modify.action.inc, function views_bulk_operations_modify_action_form on line 202:

$entity = entity_create($context['entity_type'], $default_values);

The entity id is never set in my case. Maybe it is written this way by design. I just want to be sure if there is a reason why it's not written this way instead :

    $entity = entity_load_single($context['entity_type'], reset($form_state['selection']));

Indeed, we do have the identifier information in the variable $form_state['selection']. It could even be done by leaving the previous instruction and assigning the key directly.

What do you think ? It should stay as is, 'cause it is the right design ?
Thanks for your help.
