If I go to an old revision of a page such as https://en.wikipedia.org/w/index.php?title=MediaWiki_talk:Common.css&oldid=765550835, the user interface says "edit source". This will allow me to edit the source at this point in time, so the label is technically accurate, but the much more common use-case of clicking this tab from an old revision is to revert to an older version of the page.

Can/should the user interface be made clearer to explain this? For example, we could label the tab "revert to this version" instead of "edit source".
