Research direction
Reproduce the issue in mapbox-gl-js 0.49.0 with a raster layer backed by the Google map source, then call map.setLayoutProperty('layerID', 'visibility', 'none') while watching the network console. Trace the visibility update and raster request handling; done means hiding the layer does not trigger a duplicate HTTP request.
