maxZoom: 0 is ignored

[FiodarHmyza]

mapbox-gl-js version: 3.9.0

browser: Chrome 131.0.6778.205

Steps to Trigger Behavior

1. Open example https://docs.mapbox.com/mapbox-gl-js/guides
2. In the suggested JS editor, set maxZoom to 0:

   const map = new mapboxgl.Map({
       container: 'map',
       style: 'mapbox://styles/mapbox/streets-v9',
       projection: 'globe', // Display the map as a globe, since satellite-v9 defaults to Mercator
       zoom: 1,
       maxZoom: 0,
       center: [30, 15]
   });

Expected Behavior

Maximum zoom level 0 should be accepted as any other possible levels: user should not zoom in beyond this level.

Actual Behavior

maxZoom is ignored like there is no value at all.

Possible solution

Most likely, the existence of a property is checked with simple JS if (property) code. It will produce false for 0. Additional check on 0 value should work: if (property || property === 0).

Temporal workaround

Set maxZoom to 0.0001. It should pass existence check and then it will be rounded to 0.
