Short description of error
Adding a Bone to an Armature Layer doesn't trigger a Depsgraph Update initially

Exact steps for others to reproduce the error

Run the script below
Press M and assign a Bone to an Armature Layer: there is no update until the Bone has been removed or other layers have been assigned.

import bpy
from bpy.app.handlers import persistent

@persistent
def depsgraphUpdatePost(scene, depsgraph):
    for update in depsgraph.updates:
        print("update.id",update.id)
    return

def register():
    bpy.app.handlers.depsgraph_update_post.append(depsgraphUpdatePost)

def unregister():
    bpy.app.handlers.depsgraph_update_post.remove(depsgraphUpdatePost)

if __name__ == "__main__":
    register()
