Thanks for this great tool!

Used Version: 2.1.1 / Win / Deluxe

Error Description: Creating a clone of a group, creates a group with both (original and clone) inside.

Steps to reproduce:
1. Add 2 Blocks e.g. "block".
2. Select both and create a Group (Hotkey: G)
3. Select the Group and create a clone (Hotkey Ctrl+D)
4. Move the newly created clone. (Only the clone moves)
5. Deselect clone, and select it again.
6. The original and the clone are now both highlighted. They seem to share the same group. Moving or scaling them, changes both.

Expected behaviour: Creating a clone of a group, should create a new group, instead of merging it with the existing group.

Additional Info: Copy + Paste works as expected. (Creating a copy of the group, without any visible/logical connection to the other)
