Duped Unique Charm with Unique Tab

I dragged a unique charm from my dump stash tab to the unique tab, and it placed it in the unique tab. However, it also remained on my cursor and I was able to put it back in my inventory. After removing the item from my unique tab, I now have two.

I was unable to replicate the issue again with a few minutes of testing but this could be problematic if it works for any unique and is reproducible.

Woops, meant to put this in POE2's forum. Will repost, please delete
