Describe the Bug

Hi. I'm contributing to a mod about portals and I wanted to add Create mod compatibility to this mod. Compatibility works fine when you're teleporting between different dimensions. However, when I've tried to make portal pointing to the same dimension, 7 tracks in front of the portal got invalidated (you cannot place trains or stations on them). During investigation I've used track graph debugger and found out that graph is connecting from the middle of the track right to the second portal (screenshot).

Reproduction Steps

1. Make a portal pointing to the same dimension (not different like nether or aether)
2. Place track in front of the portal
3. Graphs are merged without using portal

Expected Result

Graph should probably take into account existance of Portal and shouldn't connect straight to another side from the middle of the track
