Improved dragging is not working

[kjyv]

If I enable the feature "Improved Component Dragging", the blue line appears in a similarly small range only but also the cursor now has to placed a bit off the actual place - actually making it harder to move components. The blue line is a bit thicker if I disable the feature and it works as before (I think).
I expected it to snap to either end of the component the mouse cursor is on depending which is closer. There should not be a state where there is no blue line at all.
