Summary: When typing in a second username in the 'Add to collection' screen in the DAM, the backspace button does not work.
Steps to reproduce (Chrome/Safari):
Go to a Collection and click on the Edit icon.
Search for a user to add. Add the user.
Change user's permissions to Modify
Search for a second user, but before adding, try deleting what has been typed.
It will likely undo the permissions, but not delete what has been typed.
