If the user creates a widget with an animation that fades the widget out. This effect will not carry over into a 3D widget. The 3D widget goes directly from 1 to 0 or visa versa.

Steps to Reproduce
  1. Open the editor
  2. Create a new widget blueprint
  3. Add an image to the designer tab (make it large so it's easier to see)
  4. Create a new animation
  5. At time 0.0 set the opacity of the image widget to 1 and key it on the timeline
  6. At the time 3.0 set the opacity of the widget to 0 and key it on the timeline (image for reference)
  7. Go to the event graph and create the blueprint in the attached image (plays the animation on event construct and loops)
  8. Create a new actor blueprint
  9. Add a widget component to the actor blueprint
  10. Add the Widget blueprint that was just created to the widget class for the widget component
  11. Compile and save
  12. Add actor to the level
  13. Play in Editor
  14. Notice that the widget does not fade but appears to flicker between an opacity of 1 and 0

Expected: the image would fade over 3 seconds
Result: The image appears for 3 seconds and then disappears all at once
