Steps to reproduce:
- Create an Activity and set its "expect completion by" date
- Open the Calendar monthly view. The expected completion should appear as a course event.
- Click and drag to move the event to a different date.
- Open Activity settings for the activity.
- The "expect completion by" date will not match the new date set on Calendar; it will still be the original date set at activity creation.
After moving the event on the Calendar, the "expect completion by" date within the Activity settings should update accordingly.
