Hardly. It was his job to resolve the issue, that's what he was employed to do. That wasn't Rachel's job, and in fact she went out of her way to explain to him how to resolve the issue.
What would you have her do? Do the fix herself? If so - phooey to you, that wasn't her job and she shouldn't have done so. If you don't think she should have done the fix herself, then the only other recourse here would be for Rachel to not give any help at all and let them struggle on themselves.
The developer attempted to push out a change that Rachel had already said wasn't acceptable, then made a massive fuss to his managers and attempted to make her look bad. Then Rachel explained, in detail, why she said no - developer got transferred due to his own incompetence. I can't feel any sympathy for that developer!
