The Back link doesn't appear for the Attachments tab unless another tab is first clicked, and then the Attachments tab is clicked again. Clicking the Add Attachments button will also cause the Back link to appear. This occurs upon clicking "X Attachments" underneath the text of a page, where X is the number of attachments. This also occurs on child pages.
