研究方向

Investigate the save/load state logic for layer visibility. The bug triggers when hiding a layer on a new document; the saved state becomes inconsistent after unhide/hide cycle. Look in the document serialization code (likely in src/document/ or similar) to understand how visibility flags are stored and restored. Check if there's a missing or incorrect update to the 'is saved' flag after layer visibility changes. Reproduce the steps in the issue and add debugging to trace the state changes.
