Animation Blueprint with Shared Transition "marked" dirty

Animation Blueprints which contain a shared transition used to transition between two animation states will be marked as "dirty" every time the blueprint is compiled and re-opened.

1. Create a new Third person Blueprint project.
2. Create a new Animation Blueprint based on an Animation Instance Class,  using the UE4 Skeletal Mannequin.
3. Add a State Machine node to the AnimGraph, and create 2 state nodes within the New State Machine.
4. Create a transition between the two states in either direction.
   Save the Animation Blueprint and close the editor, then re-open the BP
5. Select the Transition and click Promote to Shared and give it any name you like.
6. Create a new Transition in the other direction between the two State nodes, and choose to re-use the Shared Transition created in step 5.
7. Save and close the BP.  Upon re-open..

Result: you will notice that it has an asterisk in the Content Browser as it has been marked dirty even though nothing has changed.

Expected: No asterisk, Blueprint would compile clean.
