[Bf-python] Some bpy.types Custom Properties Are Read-Only

[Khalifa Lame]

Hi. I need assign custom properties to mesh vertices, edges and faces. It
doesn't throw any errors on creation of the custom props, but after they've

Is there a reason for this? Is there a known workaround or hack? I really
