v0.43.0, chrome

Issue description
Layers do not share WebGL context, which creates glitches when a map has more than one 3d layer. For example a buildings layer with a 3D line will not hide the line behind the buildings.
In particular, I am implementing a 3D terrain layer but this layer will not hide (behind mountains) any other 3d element in the map, such as buildings.

Please provide a reproduction URL (on any jsfiddle like site)
The following example fraws two vector layers. Due to the WebGL context not being shared, the rendering is wrong.

Yeah, indeed.
We are working on a new layer to solve this issue in a decent way.
It should be ready in 1 or 2 months, I will update here once it's ready.
