Picklist: Item is placed at negative index in event.target

[omikader]

Describe the bug

I stumbled onto this strange behavior where moving an item from source -> target, repositioning the item, moving it back to source, and then trying to re-order the target list results in the target array having undefined values and items placed at negative indexes, like -1.
