Bug Description

Hi,

steps to reproduce:
1. Route a differential pair.
2. Use the differential pair length tuner to make the differential pair longer.
Result: Tracks that make the differential pair cross each other at the beginning and at the end of the length tuned segment. See the attached screenshot.

Maybe it's somehow related to a fact that, while routing, the ratsnest line for the positive track is blue and for the negative track it's red. Or is that intentional?
