Worked: (newest version of Blender that worked as expected)

Short description of error
When using the ungroup operator either through the shortcut or menu the group rather than ungrouping, just duplicates your current node tree.

Create a node group with any nodes in any node editor and attempt to ungroup it.

A git bisect seems to point towards rBfdc4a1a590d8befb1ff9ab1de3f02d82aa46d539 as the culprit for the Ungroup issue.

Thanks again for catching a mistake! I'm not sure about the issue with assets you mentioned, it seems to work okay for me. If that's still there, could you submit a separate report about that?
