I had this several times where I added a label or changed a font-size and hit in the side-bar text-field which caused the node and it's relationships to be duplicated.
I believe this happens because Enter is submitting a form, and the "duplicate" button gets activated as a side effect. I probably need a generic event handler to preventDefault() in all the right places.

Nothing in the JS console.
