Description
While generating pbf tiles from the tippecanoe of the following Geojson file and viewing on mapbox-gl tiles distortion(breaking) is obseved at lower zoom levels.
[100_M_BUFFER.zip](https://github.com/mapbox/tippecanoe/files/11915567/100_M_BUFFER.zip). I am using following settings in options given to tippecanoe
```let options_obj: any ={
minimumZoom: 1,
readParallel: true,
buffer: 127,
simplification: 1,
layer: layer_id,
noFeatureLimit: true,
noTileSizeLimit: true,
noTinyPolygonReduction: true,
preserveInputOrder: true,
noLineSimplification: true,
extendZoomsIfStillDropping: true,
force: true,
dropRate: 0,
};```

Research direction
Start by reproducing the distortion with the attached 100_M_BUFFER.zip and the listed tippecanoe options, then inspect the generated PBF tiles in mapbox-gl at lower zoom levels. Compare behavior while isolating the zoom, buffering, simplification, and feature-dropping settings. Done means the supplied data renders without tile breaking at lower zooms or the limitation is clearly documented.
