Sharp edges in end terrain generation

See attached screenshots. Sometimes, sharp edges run continue for more than what would be considered normal.

Example:

• Seed: 4443456532649347071
• Coordinates: /tp @p 68 73 74

Noteworthy: This edge runs right along the middle of the chunks, 8 blocks being filled with endstone and 8 blocks being filled with air.
