Moving a Widget in UMG by dragging the position value results in Stuttering and Jerking

This is a regression. Tested in //UE4/Release-4.27 CL#18319896

Moving widgets within UMG by dragging the position value with any sort of speed results in the widget stuttering and jerking around. 

1. Create or Open any project
2. Create a new Widget Blueprint(in the content browser: right-click > User Interface > Blueprint Widget)
3. From the Palette panel add a Canvas Panel widget to the Hierarchy
4. From the Palette panel add a Text widget to the Hierarchy under the Canvas Panel
5. In the Text widget's Details panel Left-Click and Drag the Position X value left or right

Expected Results:

As in 4.27.2 the widget should smoothly slide back and forth.

Actual Results:
The widget stutters and jerks around.
