Research direction

Start with the linked JSBin reproduction using mapbox-gl-js 1.12.0, Playfair Display 700, and a large font size in Chrome on macOS. Compare the thin glyph edges shown in the demonstration with the expected fully readable rendering. Done means the reported Playfair Display rendering issue is resolved and the reproduction no longer shows the affected strokes.
