Research direction
First reproduce the behavior in mapbox-gl-js using a line feature, terrain enabled, and zoom changes, comparing it with terrain disabled. Trace the terrain and line-width rendering entry points to find the delayed stepped update; done means line-width changes continuously and consistently while zooming with terrain active.
