Description
**mapbox-gl-js version**: 3.7.0
**browser**: Google Chrome 130
### Steps to Trigger Behavior
Create a map instance with a filled Polygon containing three sets of coordinates.
1. The entire world - `[[180, 90], [-180, 90], [-180, -90], [180, -90]]`
2. A triangle - `[[149.4, -37.3], [152.5, -32.1], [150.1, -32.6]]`
3. A triangle within the previous one - `[[151, -32.8], [151.5, -32.8], [152, -32.6]]`

### Expected Behavior
I acknowledge there might be different interpretations of whether the inner triangle should be filled or not, but I expect the corners of the resulting shapes to be limited to the supplied points.
### Actual Behavior
At a certain zoom level, there is a triangle that seems unrelated to any of the input points. I've used markers to indicate the input points.

Research direction
Reproduce the issue in the linked CodePen using mapbox-gl-js 3.7.0 in Chrome 130, with the world polygon and the two nested triangles described in the steps. Vary the zoom level and compare the rendered corners with the supplied coordinates; done means the unrelated triangle no longer appears and the resulting polygon geometry matches the reported expected behavior.
