Was the case in 2.7x too:

Luckily it has no bearing on the resulting loop cut, but is a strange small display glitch with the loop cut tool and this exact type of geometry.

So, is it a regression?

Well, no. That's what I just wrote - this has always been the case. It is a bug, but not a new one. It should be fixed, but it's a fairly harmless display glitch that happens in rare instances. Not sure how to prioritise these kinds of things.

I have re-triaged this report and can not reproduce it. (original .blend file missing?)
Can you please check if this is still an issue in latest build?

I believe the bug is in: view3d_preselect_mesh_edgering_update_edges_from_edge
in editmesh_preselect_edgering.c

Looks like its creating an extra edge at the end. I don't much about how BMesh edges work but I'd liked to take a crack at it over the next couple of days for learning purposes.
