Inconsistency of /clear in creative mode

The problem concerns the behavior of the /clear on items in cursor in creative mode.

Behaviors wanted:
   - the item in cursor can not be clear when it comes from the creative inventory.
   - the item in cursor can be clear when it comes from a container or is picked up.

Unwanted behavior assumed:
   - the item in cursor can not be clear when it comes from the survival inventory.

An example where this inconsistency appears:
When a creative player takes an item from his survival inventory, do an action and clear the item.
Currently, the item is not clear because it is held by cursor.
