admin level 10 boundaries are rendered on top of other admin levels

Rendering of admin level 10 boundary with lower admin levels leads to artefacts:

My guess: The ordering introduced in #1107 sorts the 10 between the 1 and the 2 which leads to admin level 10 being drawn over the other admin levels.

Good guess, I would have never thought of that but I think you're right.

No idea when, but I think this has been fixed (see https://github.com/gravitystorm/openstreetmap-carto/blob/master/project.yaml#L1367).
