End terrain generation completely breaks past X/Z = 370,720

When traveling past X/Z = 370,720 in the end dimension, one can see that the terrain generation stops entirely. At X/Z = 524,288, terrain generation resumes before it eventually stops again. This bug has been present in Minecraft since snapshot 18w46a.

Here is a YouTube video by AntVenom where he explains the bug in detail: https://www.youtube.com/watch?v=91Feq0dHw28
