Cannot key font material for UMG Widget animations

1. Create a new widget blueprint
2. Add a text block to the designer and select it
3. Expand Appearance > Font in its details panel

RESULT

There is no button for adding a key next to the Font Material Parameter. In 5.2 there is. 

Additional Repros:

1. Create a new level sequence
2. Add a static mesh cube to the level sequence
3. Add the static mesh component from the cube to the level sequence
4. +Track and look for Body Instance->Physics->Simulate Physics

EXPECTED: Simulate Physics is available to keyframe.
