Using the transform gizmo to scale a blueprint component will break the functionality if scaled to 0.0 and released.

If the scale value is directly set to non-zero value, gizmo can be used again to adjust scale.

Steps to Reproduce
  1. Open UE4 Editor
  2. Add Blueprint to project based on Actor
  3. Add cube component to blueprint
  4. Select transform gizmo and switch to Scale tool (R)
  5. Grab scale tool in X axis and scale down to 0
  6. Release scale tool

Attempting to scale the cube component out with the scale tool no longer functions.

Component can be scaled to 0.0 and into the negatives with gizmo
