Billboard "Is Screen Sized Scaled" Only works with negative screen size

Billboard components do not retain 'screen size' size when viewed from a long distance.

When negatively scaled (ex: -0.005) they will still be visible from long distances.

1. Add Billboard Component to a Blueprint
2. Place BP in Level or view in Viewport
3. Enable "Is Screen Size Scaled"
4. Increase Screen size to value above .005 (default value is .0025, size appears to clamp at .005)
5. Decrease Screen Size to a negative value

Result: Billboard size is clamped at .005 in positive, Billboard is not clamped in negative.
