Research direction

Start with the examples app and the Mapbox logo view, reproducing the issue on an iPhone XR rather than only in the simulator. Compare the affected SDK versions and inspect how views added above the map are rendered. Done means the horizontal grey line no longer appears above the logo on the affected device.
