[backport core/1.32] fix: remove LOD from vue nodes (#6981)

## Summary
Backport of #6950 onto core/1.32.

- cherry-picked 4b87b1fdc
- resolved conflicts by taking the upstream PNG expectations and
removing LOD bits from WidgetMarkdown while preserving cloud-specific
padding

## Testing
- pnpm typecheck
