Language cannot be set, if zoom is smaller than 6 when creating the map

[WindLi001]

I found an interesting issue.

• If I create a map with zoom isn't set (that is, zoom is default), or is set to a value smaller than 6, and then set the language to Chinese,

    map.current = new mapboxLibrary.Map({
      zoom: 5,
      container: mapContainer.current,
      style: isDarkMode()
        ? 'mapbox://styles/mapbox/dark-v10'
        : 'mapbox://styles/mapbox/streets-v11',
      ...mapboxOptions,
    })

    map.current.addControl(new MapboxLanguage({defaultLanguage: 'zh-Hans'}));

then an English map is shown.

    map.current.addControl(new MapboxLanguage({defaultLanguage: 'zh-Hans'}));

then a Chinese map is shown.

The code above is a part of project photoview [https://github.com/photoview/photoview], and in the ui/src/components/mapbox/MapboxMap.tsx. You can find the context there.

Furthermore, I find this issue only happened when I set projection to global and zoom smaller than 6. That is,

    map.current = new mapboxLibrary.Map({
      **zoom: 5,**
      container: mapContainer.current,
      style: isDarkMode()
        ? 'mapbox://styles/mapbox/dark-v10'
        : 'mapbox://styles/mapbox/streets-v11',
      ...mapboxOptions,
    })

and

  const { mapContainer, mapboxMap, mapboxToken } = useMapboxMap({
    configureMapbox: configureMapbox({ mapboxData, dispatchMarkerMedia }),
    mapboxOptions: {
      **projection: {
        name: 'globe',
      },**
    },
  })

, and then
map.current.addControl(new MapboxLanguage({defaultLanguage: 'zh-Hans'}));
an English map but not Chinese map is shown.

I found same issue when creating the map. I want to set the laguage as English, but alway show some Chinese labels.

• I try this way but not work, still some Chinese labels shown at left hand side

map.setLayoutProperty('country-label', 'text-field', ['get', 'name_en'])

• and then I found that there are different labels, all of them have to set as English.

    let labels = ['country-label', 'state-label',
        'settlement-label', 'settlement-subdivision-label',
        'airport-label', 'poi-label', 'water-point-label',
        'water-line-label', 'natural-point-label',
        'natural-line-label', 'waterway-label', 'road-label'
    ];

    labels.forEach(label => {
        map.setLayoutProperty(label, 'text-field', ['get', 'name_en']); 
    });
