Steps to reproduce:
- Enable the Develop menu.
- Go to Develop-->User Agent.
- There is a selectable "Custom" option, but no way to specify what the custom user agent should be.
Expected behavior:
In Safari, when "Other..." is selected from Develop-->User Agent, a dialog prompts for the custom user agent string to use, displaying the current user agent string to use as a starting point.
