When using 3D Terrain raster layers with an id starting with a NUMBER forces the layer order to the bottom

mapbox-gl-js version: 3.3.0

Steps to Trigger Behavior

1.Use Mapbox Terrain-DEM v1
2.Add an initial raster layer that should be on the bottom with an id starting with a string id:"A5000". Then add another layer that should appear on top with an id that begins with a number ie id: "5001"
3.The second layer that should have been on top is now underneath the layer id:"A5000".
4. mapbox.setTerrain(null); will correct the layering problem

Expected Behavior

Layers with id's that begin with a NUMBER should respect layer ordering when using 3D Terrian.

Actual Behavior

Layers with id's that begin with a number are pushed to the bottom of the layer ordering in 3D Terrain mode.

Using the newley impletmented slots also does not resolve the layering problem
