I'm struggling with the exact same component and problem. Polygons work fine, but linestrings and points do not. I have tried every online example I can find but I can only get a polygon to paint, the others don't appear on the map. Additionally, if you override the layer styling, so really weird things start to happen and the map doesn't always paint the general geography. Coordinates/points will still appear, but neither the polygons or base map will.
Any suggestions or help from ReTool? ilsemaj, did you make any headway with this after posting your original issue late last year?
