When showing an old revision of an item, the page title is set to the item's *current* label. The item's label as it was in that old revision visible anywhere.
The old title should be used at the top. Or, even better, the top title should be set to Old revision of "Foo" with the current label, and below the revision info, there could be another <h1> showing the old label.
