Short description of error
Strange behaviour of connected proportional editing on a cylinder mesh.

When moving a ripped off edge of a cylinder with connected proportional editing, falloff curve breaks in the middle. It's hard to describe in text, so I recorded a video showing this issue: https://youtu.be/_A5hSb3srwA
This issue happens with all falloff modes except constant and random.
I tried to reproduce this with circle, sphere and plane meshes with cuts in different places, but it worked fine.

Exact steps for others to reproduce the error

  1. Create a cylinder.
  2. Rip one edge off.
  3. Move that edge with enabled connected proportional editing.

EDIT:
Actually i managed to reproduce this with a plane.
It matters if you subdivide it with right-click->subdivide or with loop cuts. The latter one causes the issue, the first one doesn't.
Also this happens if you move any other edge of the loop cut.

Also I noticed that that break point appers to be exactly 1 unit far from seelcted edge.
