Not all areas of KML file get converted

To the people behind ToGeoJson:

First of all, because it is not done enough, I just want to express how much I greatly appreciate your work and how much it helps other people out there including myself when they have to deal with KML files.

The problem that I have now is that - for the first time - I have a KML file that is not correctly converted to GeoJson when I run it through your script. One particular polygon, or at least the majority of it is missing.

Validating the KML and also mapping it, show that there are no apparent issues with the whole KML-file and also that this particular missing polygon seems to be just fine.

However, once it is converted the GeoJSON, the mapped GEOJSON has a hole and the specific area is only shown in parts.

Here are the screenshots of the KMLs mapped with https://mygeodata.cloud/:

And here are the GEOJSONs mapped with http://geojson.io

I would be very thankful, if you can have a look into the issue and explain to me what went wrong.

Best,

Start by downloading the linked KML for the missing area and the entire file, then reproduce their conversion and compare the resulting GeoJSON with the source polygon. No files, tests, or entry points are named; done means identifying why the area is omitted and confirming that the converted GeoJSON contains the full polygon without the reported hole.
