text: Technically in this case it's fine, you're only not allowed to map for the default OSM renderer -- but drawing for other renderers like https://demo.f4map.com/#lat=37.8055085&lon=-122.2725949&zoom=19&camera.theta=40.13&camera.phi=-8.594 this is fine...
  I can see this is probably not being rendered correctly in f4map but I'm not sure how it looks like in real life to make a fix...
