Blender Version
Broken: It has been broken for a long time
Worked: (newest version of Blender that worked as expected)

Short description of error
The radius center will be on the 3D-Cursor or Active Element, when the influence is not actually calculated from that position.

Exact steps for others to reproduce the error
Set Transform Pivot Point to 3D-Cursor
Enable Proportional Editing
Move the 3D Cursor far away from the default cube
Enter Edit Mode on the default cube
Move a Vertex

Might be related to #110167 (comment) because there is a misplaced gizmo there too when Transform Pivot Point is 3D Cursor.

There is no perfect solution to this because the influence radius might be calculated from many individual positions.

Drawing an influence radius for every individual selected element can get cluttered fast. And drawing it at the median point of the selection can have edge cases too, when two islands of selections are edited. But it would arguably be closer to where elements move in most cases.
