[Issue] Undo does not restore Seams

[Hiiamwilliam]

Detailed description of your issue

On a Generic Model, if I manually set seams on a Mesh to either Join or Divide, delete the mesh, then Undo, the manually set seams will be reverted to Auto. I expected to have the seams as I set them before.

(This is version 4.6.4, up-to-date)
