mapbox-gl-js version: 0.52.0

Steps to Trigger Behavior

Upgrade from 0.51.0 to 0.52.0

Link to Demonstration

You can compare results on this two codepens :
0.51.0 - https://codepen.io/pakb/pen/VgErjv
0.52.0 - https://codepen.io/pakb/pen/jdeayx

As you can see south of the lake, the label Thonon-les-Bains is now hidden under our data in 0.52.0.
I don't see in the changelog anything that would hint me to what change has produced this.
Are we doing something wrong with how we describe our style or is it a bug?

@pakb thanks for the report! this seems relevant to #7908, which actually prevented symbol layers under opaque fill layers to show through. Before the fix, the symbols would appear above the fill, regardless of position in the layer stack.

It's possible that your map style exploited this earlier antipattern -- can you verify that the symbol layer for your label is above the fill layer for the lake?

I think @peterqliu meant to reference #7612

Ok, that’s the thing.
We’ve put everything OSM before our layers. Then it’s our data which is not correctly set and not a bug, I close this issue.
Thanks for pointing me out
