2-Point Arc Tool?

In this video, should the Measurements toolbar accept input after finishing the arc? I’m not looking for work-arounds - I am looking to report a bug if it IS a bug.

The key is not moving the mouse between the final 2 clicks. If you do move the mouse, then the Measurements box is available on completion of the arc.
