Short description of error
I noticed if I will use bpy_extras.mesh_utils.mesh_linked_uv_islands(mesh) it will not take into account 3d islands
It would be nice to have an option to separate 3d islands and UV shells too. You could add a variable in the method.
Something like mesh_linked_uv_islands(mesh, separate_in_3d=False) .
I did 3d separation in my blend file. Could you check it, please? May be you could add it into blender.

tmp1.blend

Exact steps for others to reproduce the error

Open my file
run my script
check console of UV Shells.
You will see that my modification will have 6 UV Shells when the default one will have only one UV Shell.
