Polygon cut is appearing as an additional polygon #89

As you can see from this picture: (location of the issue: http://localhost:8080/?debug=true#6.62/23.78/-76.40)

The pointed out outline should be a cutout, and not solid. This indicates that the cutout is being treated as a seperate polygon

Provided are three wkt's of the region.

Created a program to break down the process and generate intermediate representations. However, was not able to replicate the issue. Trying location 2/1/1 as it has the same issues.

The issue is not in makevalid but the mvt encoding step.
