iOS client ignores style.json `encoding` - only considers tile.json `encoding`

iOS Version

26.5

Device

Simulator (though I assume all devices are affected)

What happened?

MTL tiles fail to render unless I have encoding: "mlt" in the tile.json - even if I have encoding: "mlt" in the style.json

The style spec implies that putting it in the style.json should be sufficient.

In fact, I wasn't expecting the declaration in the tile.json to have any effect (but it works for both js and native). Is that documented somewhere?

Steps to reproduce

I've set up a demo here: https://michaelkirk.github.io/mlt_style_demo/

In particular, see "Case #3: mlt_style_encoding · no_tile_encoding" in the demo
style.json: https://michaelkirk.github.io/mlt_style_demo/styles/mlt_style_encoding_no_tile_encoding.json
tile.json: https://michaelkirk.github.io/mlt_style_demo/sources/no_encoding.json
