Reproduce the issue in ComfyUI 0.25.0 with ComfyUI_frontend v1.45.15 by resizing a Bernini Conditioning node after adding a reference image, saving the workflow, and reopening it. Trace the workflow save and reopen behavior for this node; done means its resized dimensions persist without reverting, and the reported crash is not reproduced.
