Symbols with line placement not correctly projected near south pole when using globe and terrain

[az0uz]

mapbox-gl-js version: v2.15.0

browser: latest Safari / Chrome / Brave, on Mobile and Desktop

Steps to Trigger Behavior

1. Setup Mapbox with globe projection
2. Add terrain with some exaggeration, ex: 8.0 (larger exaggeration will show larger placement error)
3. Add a geojson line near the south pole (ex: -84 latitude) with a string property to use as a label
4. add a line style layer to draw the line
5. add a symbol layer that uses 'symbol-placement': 'line' layout property
6. Move and pan around the south pole to visualize the label

Expected Behavior

The Label should be placed at the globe surface, along the line

Actual Behavior

Multiple renderings of the label are present, distorted above the surface, the distortion and distance to expected placement intensify when the symbol is closer to the south pole and with larger terrain exaggeration
