Description
**Describe the bug**
One layer with two polygons is showing only one at a time at earth-size zoom levels.
**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://kepler.gl/demo
2. Drop attached GeoJSON file [minimal-example.json](https://github.com/user-attachments/files/17147875/minimal-example.json)
3. Navigate map keeping -180/180 line at the center of screen
4. Scroll left/right

Research direction
Start by loading minimal-example.json in the kepler.gl demo and reproducing the issue with the -180/180 longitude line centered while scrolling. Trace the GeoJSON polygon rendering path to determine why only one polygon appears at earth-size zoom levels; done means both polygons remain visible together in the same layer.
