As someone who browses and patrols wishes, I want to see the title at the time of the new (i.e. righthand in LTR) revision of a wish while looking at a diff so I can quickly have a sense of what the wish is about without returning to the current version of the page.

Derived Requirement

Ensure that when viewing a diff for a wish, the title of the wish corresponding to the newer revision (right-hand side in LTR contexts) is clearly displayed, allowing users to immediately understand the context of the change without navigating back to the current version of the wish page.
