Unable to Paste Partially Copied Mesh Between ArtMeshes in 5.3.02 beta1
When I try to partially copy a mesh from ArtMesh A to ArtMesh B, I am normally able to paste the mesh without any issues. I tested this behavior in Live2D Cubism 5.2.03 and 5.3.01, and the mesh pastes correctly in those versions. However, when I try the same process in 5.3.02 beta1, a notification appears when pasting. Even after confirming the notification, the mesh cannot be pasted as expected.
I am reporting this because this method is part of my normal workflow for meshing, so the difference in behavior affects how I usually work.
I have attached a video to demonstrate the issue more clearly.

Since the version tested is still in beta, I am not sure if this behavior is already known or not. However, I thought it would be helpful to report it in case it has not yet been identified.
