Polygons incorrectly overlap when using terrain with 512px images

[neodescis]

It seems that MapLibre 5.x is rendering polygons (and possibly other things) incorrectly when using terrain tiles set to 512px. Note that the actual image size doesn't seem to matter; it's the size that is provided to MapLibre. In the jsbin below, this can be fixed by setting the tile size to 256px (even though the images are 512px), or reverting back to MapLibre 4.x.

I based the linked jsbin on the MapLibre terrain example. Interestingly, even though the tiles are 512px, the example's terrain is set to 256px. I'm not sure why that is.

I assume this was caused by the new globe functionality, but it does not require the globe projection to be enabled.

maplibre-gl-js version: 5.1.0

browser: Chrome 132

Steps to Trigger Behavior

1. Add terrain with 512px images
2. Add large polygon over the top that spans multiple tiles
3. See weird overlap

Expected Behavior

Polygon should be rendered without overlap

Actual Behavior

Overlap around tile boundaries

The provided example and the description above doesn't mention the need for globe, should the globe tag be removed then?

I added globe purely because I believe the globe changes caused this; we can remove the label if you like though!
