Description
These one-way arrows are drawn by rendering road layer as symbols, and using a unicode arrow as the symbol text. Why is one symbol aligned perfectly in the road's middle, while the other is significantly off-center?

Research direction
Start by inspecting the linked styles/emerald-v7.json road-layer symbol definitions and comparing the two one-way-arrow configurations. Then trace symbol rendering and alignment in mapbox-gl-js; done means explaining the differing offsets and correcting the behavior so the arrows align consistently along the road.
