Comment 6 for bug 1735835

The record buckets UI de-dupes records to ensure you don't have duplicate records when adding to pending already, but the copy buckets don't appear to have the same functionality. I erred on the side of working with how both UIs already functioned when adding items to pending. That may be worth opening a new bug for, if it's not intentional.

Nice catch on that stray console.log, I'll amend it out.
