In Firefox, when creating a new item, if you select an Item type (Freestyle, Pipeline, ...), then fill the Copy from box and select an existing item, and hit create, a new item is created rather than a copy.

NOTE: when you select the Copy from or start typing into it, the item type record ("Pipeline" for example) looses the focus so this is very unexpected and a bug.

Cannot reproduce in other browsers I tested (Chrome / Safari)

How to Reproduce

In Firefox:

• Create a new pipeline with New Item > Pipeline. and add a configuration such as Discard old builds
• Click on Pipeline option
• Click on Copy from and type / select the previously created pipeline.
• Hit Create
