Snap to nearest spline point no longer working in 5.6. Right clicking on a spline point and using the option “Snap to nearest spline point" will no longer snap that point to any nearby spline and will sometimes cause the spline to snap to itself.

Context:
When editing SplineComponents in the level viewport, right clicking a spline point has a context menu action "Snap to nearest spline point".

Problem:
The problem is, Snap to nearest spline point no longer working in 5.6. Right-clicking on a spline point and using the option “Snap to nearest spline point” or pressing Shift + P on a spline point will no longer snap that point to any nearby spline and will sometimes cause the spline to snap to itself.

1.) Download and open repro project uploaded in ticket
2.) Ensure level "L_TestMap" is opened (should be opened by default when opening project), if not go to Content Drawer > Content > L_TestMap
3.) In the Outliner, double left-click on SplineActor2 to place it in view
4.) Right-click on the leftmost point of the spline and in the menu left-click on Snap/Align > Snap to Nearest Spline Point
(or left-click on the leftmost point and press Shift+P)
Observe: It doesn't attach to the nearest spline point
Expected: It attaches to the point to the left of it as that point is the closest
