Short description of error
In sculpt mode, Scale tool with pivot center set to cursor does not work as expected. The area close around the scaling center seems to go away from the gizmo.
Exact steps for others to reproduce the error
The surface close to the pivot point should be the least affected but it translates along the axis of scale.

Transforming in sculpt mode works by applying the same transformation that is happening to the sculpt pivot (a internal point were the transform gizmo snaps by default) to all the vertices in the sculpt + mirror operations. If you change the pivot origin, you are not scaling the vertices form that pivot, but scaling the sculpt pivot from the 3D cursor and the copying the transformation to the vertices. That is why it looks like it is moving.
