I have some code to implement this at https://github.com/Sgeo/blender-web3d-fixes. Had some trouble extracting just the relevant commits into a patch though.

But what I'm doing there is duplicating the mesh, flipping normals then joining. I don't know if that's appropriate. The exporter for solid=FALSE into X3D just checks material use_backface_culling.

It seems the code declares this as a limitation indeed. I would discuss this with the developers first before submitting a patch if it is not straight forward.
