inconsistent/unexpected transform orientation when in Normal Orientation mode for multiple selected

While in Normal Transform Orientation mode. Create plane, go into edit mode, select two edges, rotate on the z axis. The transform orientation displayed is not the averaged orientation of each edge.

Normal Orientation for multiple selected edges is incorrect. Single edges are correct but two opposing edges select on a plane do not produce the same normal orientation as the face of the plane.

Here is an example of the axis not updating when I rotate the geometry.

I would suggest testing the normal orientation and how it behaves with edges and see for yourself. I'm not sure if this is a bug or a limitation.

The normal is shown by the Z axis. If you have a symmetrical object, two opposite elements have oppositely directed normals and their average is zero.

@jenkm It seems to show correct x,y coordinated too for single edges and I would expect that to also work when multiple edges are selected?

In this case the normals point in the exact opposite directions. The average of the two opposing directions cancel each other out, leaving you with no normal direction at all.

In this instance, use Face Select mode and select the face itself to move along the normal.
