System Information
Operating system:
Graphics card: Intel

Blender Version
version: 2.80 (sub 74)

Short description of error
The scaling on major axis is pretty bizarre given that the object's scaling does not scale from where it is supposed to be, which is the cursor in this case.

Exact steps for others to reproduce the error

Open the attached filea and scale the torus in Y, using the Gizmo. See how the scaling behaves.

The pivot and the orientation is set to the Cursor. However orientation type does not make a difference in the scaling issue.

Also checkout the attached video

I have the same issue in blender-2.81-19547236355d-windows64
Even when i apply rotation the scaling is strange

I think that this has something todo to do with the rotation but the main issue is with the Cursor being as the pivot point. I can actually replicate this in 2.79.

The scaling firstly does not respect the the pivot's precise location then there is unexpected scaling direction.

The issue can be seen most clearly when the transform orientation set to Global or Cursor and the Pivot is set to cursor.

The only time things seem to act expectedly when the Transform orientation is set to normal, and the pivot is set to the Cursor.

This works as intended.
In Blender an object can only be scaled towards its axis.
Therefore if the axes are not well aligned, an approximate result is obtained.
You can solve this by making a parent with another object but this aligned to the cursor and then scaling the parent.

Well that is fine as far as the axis goes, my biggest issue with this is the lack of snapping to Cursor center. I also do not undertand why it the scaling cant be aligned to the Cursor axis given that we now have the Cursor rotation. That would have been a resoanble expectation in versions prior to 2.80
