Cannot draw a straight diff pair segment

[Radovan Blažek]

Hi,

when you are in the diff pair routing mode, the tracks disappear if you try to route just a straight segment without connection to the destination pads.

I have made a screen record that will hopefully make it clear.

Hi Tomasz,
This fix could be applied to the 5.02 branch, that also exhibit this issue.
