Description

A couple finite edges are missing from the Voronoi diagram built for the following segments:

I'm attaching a SVG showing the Voronoi diagram. (The input segments are the contours of the grey polygon; the black edges are the finite edges of the diagram.)

It might be related to #12067, but a finite edge is missing here instead of an infinite one.
