Edit your sandbox and the article you want to edit in source mode. Copy the article to your sandbox, then publish the edit in your sandbox. Afterward, simply edit the copy you've made in your sandbox.

Note: Both the copy being made in source mode and the publishing prior to editing are important steps. By copying and pasting in source mode, you guarantee there are no mistakes with the copy itself. By publishing prior to editing, you guarantee you don't have to copy the article again if you accidentally refresh the page or something to that effect.
