Manage relationships window - arrow direction is incorrectly reversed for many-to-many relationships with a direction

The Manage relationships pop-up window incorrectly reverses the arrow direction for many-to-many relationships with a specified direction. The arrow direction is shown correctly in the Model diagram view and it's Properties pane, and in the Edit relationship pop-up.

Here's a simple repro PBIX for this issue - please review the Model diagram and then compare to Manage relationships.
