minimal zoom level incorrect for small map size

[Akiyamka]

Hello!
According to glossary zoom level = 0 must show whole earth.
But it doesn't work for map with width and height < 512px.
Example:
https://js-muk3zs.stackblitz.io

Why it's important
Small map canvas need for minimap feature.
This is a useful thing if we want to show on the map which part of the world the map is currently pointing to. Example
http://aesqe.github.io/mapboxgl-minimap/

mapbox-gl-js version:
1.3.1

Expected Behavior

zoom === 0 must show world event on small maps

Actual Behavior

zoom 0 show world only if map size more that 512px

Workaround

#map {
  position: absolute;
  top: 0;
  bottom: 0;
  width: 512px;
  height: 512px;
  transform: scale(.3);
  transform-origin: top left;
}
