BUG - Filletedge leave a small broken edge - V8

@menno, @Gijs ,

After a FilletEdge with railtype=DistbetweenRails (working like expected) I found the vertical edge cutted in 2 with a very tiny piece .

It look like the Fillet is extending the vertical surface for that tiny amount to reach the curved edge of the fillet.

Would be nice if the Fillet take care of this and merge this two part in one so the next fillet wont fail.
Thanks

Rhino has to “invent” the three-sided areas that weren’t there in the first place. I wonder what that algorithm looks like.
