Perspective Slider bidirectional Issues

Ignition version 8.1.3

When using the perspective slider with bidirectional enabled on the tag it, when you click on the handle to drag the slider it seems to write the step value instead of letting the slider move with the cursor and write out after the mouse has been released.

I would expect the slider to not write the value out until the mouse click has been released.
