Setting "Is Enabled" via the animation timeline in UMG does not appear to work at runtime

1. Open the editor
2. Create a new widget blueprint
3. Add a button to the designer tab
4. Create a new animation
5. Select the button
6. Set the "Is Enabled" setting to true at 0.0 seconds
7. Set the "Is Enabled" setting to true at 1.0 seconds
8. Set the "Is Enabled" setting to false at 1.0 seconds
9. Set the "Is Enabled" setting to false at 2.0 seconds
10. Save and compile
11. Create an onclicked event for the button
12. Set it up so that the animation plays on clicked
    (animation reference > Play animation, OnClicked > Play animation)
13. Save and compile
14. Open the level blueprint
15. Add the widget to the screen
16. Play in Editor
17. Click the button
18. Notice that either the button starts disabled or that the button does not disable itself after being clicked

Expected: The button would be clicked and would remain enabled for 1 second and then it would disable itself
Result: The button remains in whatever state it started in

Mesh throws shadows with weird corners and edges (stationary light)
