AttributeError: 'VAE' object has no attribute 'clone'

Start in extensions/sd-forge-layerdiffusion/scripts/forge_layerdiffusion.py at line 130, where process_before_every_sampling calls clone() on the VAE. Reproduce with the reported Stable Diffusion XL setup and Layer Diffusion enabled, then verify that sampling no longer raises the AttributeError.
