When a marker is not the center of the map, first zoom in without panning zooms to marker (Mapbox)

zoom_fix.js

let dragged_once = false;

map.on('dragstart', () => {
  dragged_once = true;
});

map.on('zoomend', () => {
  if (!dragged_once) {
    map.easeTo({
      center: label_list[0].lngLat,
    });
  }
});
