Converting from legacy curves to grease pencil with "Keep Original" option enabled can cause the new grease pencil ID to not be evalueated, leading to an situation where a evaluated grease pencil object would point to the original legacy curve ID as its object data. This fix added a depsgraph tag so it ensures the COW ID is the latest. Pull Request: https://projects.blender.org/blender/blender/pulls/139006
