Short description of error
In the modifier Armature that is applied to a Lattice object the button "Display modifier in Edit Mode" doesn't work. You can activate the button, but nothing happens.
Exact steps for others to reproduce the error
The problem remains even with a simpler scene.
Create a cube -> Create Lattice -> Add Lattice modifier to the cube -> Create armature -> Add Armature modifier to the Lattice -> Select some Lattice vertexes in Edit Mode and create a Vertex Group, name it after the armature bone.
Now, if we move the bone in Pose Mode and then try to work with Lattice in Edit Mode, the button "Display modifier in Edit Mode" still does not work
