Description
I need to add an arrow to a Line that has an offset (line-offset=2) to display the direction of it.
However, it seems that icon does not support offsetting!

PS: I took the jsfiddle from [this](https://stackoverflow.com/questions/46102553/showing-direction-arrow-on-line-in-mapboxgl) topic and added line-offset property to the line->paint.

Research direction
Start with the linked JSFiddle and compare the line's line-offset paint property with the direction-arrow icon behavior. Trace the relevant line and symbol rendering entry points in mapbox-gl-js, then verify that an arrow can follow the offset line; the issue is done when the direction indicator renders on the offset geometry.
