Editor fails to p4 add actor asset when WP map is checked out

Changing the world setting (or possibly anything that dirties a map) of a World Partition map that has been checked out by another user and then adding a new actor will cause the Save prompt to not include the added actor nor show up in the source control window.

Possible workaround: opening a different map will correctly list the added actor at the prompt.

• Have another user checkout a WP map.
• Now modify a world setting of the map to make it dirty and hit cancel on the dialog.
• Drag a new actor into the scene.
• Hit Ctrl + S to save and the prompt does not list the added actor.

The expectation would be that the newly added actor would be listed in the prompt. If you were to add a new actor and then modify the world setting then the actor would be correctly listed.
