I'm talking mostly about normal tabs in normal desktop browsers. When you open a new tab, it should keep the "Back" history of its parent. Safari for iOS, too, has a feature where you can temporarily go "Back" from new tabs. But like you said it breaks if you do anything else. Kind of a hack for mobile convenience rather than a true feature.
