• Fixes Bitstream with long name exceeds screen borders on the Edit item -> Bitstreams -> Upload page #4141

Description

I added our existing dont-break-out css class to the header on the edit bitstream page. I also noticed the same issue in the bitstreams tab on the edit item page, so I added it there as well

Instructions for Reviewers

• Create a bitstream with a very long name, either by uploading a new one, or editing the name of an existing one
• verify that the name now wraps, instead of moving off screen
