Short description of error
Normals are not updating in the shader editor anymore for some reason. It's totally broken several of my workflows :'(

Every version of Blender where normals usually do update in shader editor	Blender 4.0.2 where normals don't update anymore

Exact steps for others to reproduce the error

Mix 2 shaders and separate by normals.
Make some alterations to the mesh such as sculpting.
Normals are not updating like usually did in every other release of Blender.

Video example n.1: Every version of Blender where normals usually do update in shader editor.
Video example n.2: Blender 4.0.2 where normals don't update anymore.
