Cannot go from vertical-perspective to globe projection

[jonathanlurie]

maplibre-gl-js version: 5.0.0-pre.7

browser: Chrome Version 130.0.6723.117 (Official Build) (arm64) (MacOS, M2)

Steps to Trigger Behavior

1. map.setProjection({type: "vertical-perspective"})
2. map.setProjection({type: "globe"})
3. map.getProjection() still shows .type being "vertical-perspective" , instead of "globe"

Expected Behavior

After calling map.setProjection({type: "vertical-perspective"}) and then map.setProjection({type: "globe"}), we should get a .type value being "globe" when calling map.getProjection().

Actual Behavior

After calling map.setProjection({type: "vertical-perspective"}) and then map.setProjection({type: "globe"}), we still have a .type value of "vertical-perspective" when calling map.getProjection().

This means the animation is not possible from vertical-perspective directly to globe (where the animation should actually hardly show, since both are globe)

This is currently planned to be solved as part of version 5.
globe is not a projection, but a preset of vertical-perspective and mercator for different zoom levels.

Feel free to push this forward if you are eager to see this get it in.

This will hopefully be solved with:
