setting maxBounds on equirectangular projection has different results based on the map container size

[pflopez]

mapbox-gl-js version:
v3.6.0

browser:
Chrome

Steps to Trigger Behavior

1. Set two maps, one with a smaller vertical container than the other. Both maps have the same configuration, using equirectangular projection.
2. Set the same maxBounds to both maps.
3. Notice that the maxBounds for the first map and the second map do not behave the same.

Expected Behavior

Both maps should have the same max bounds, regardless of the size of the map container.

Actual Behavior

The max bounds of each map are different.

In a way, related to #12391, as Im trying to manually fix the extraneous empty space issue via setting max bounds.
