Fix order position on list when ordering items in groups

When you have 3 items selected on a list being their position on the list(from top to bottom): 1, 2 and 4, when you select to move up, the 4 should pass to 3 with the 1 and 2 maintaining their position.

What is happening is that the item 4 is passing to 2 and the 2 to 3, only the 1 its maintaining its position.

How to reproduce

• have 4 or more files inside an ordered folder
• select the items on the 1st, 2nd and 4th position on the list
• click on move up
