I am trying to VEdit https://en.wikipedia.org/w/index.php?title=User:Elitre_%28WMF%29/Sandbox&oldid=573480590&veaction=edit , which is a blank version of my sandbox. There's a lot of white space between the title of the page and the point where I can start adding text, and although the source editor says the page is really empty, looks like there's still something there.
If I hover with the mouse right below the comma in the tagline "Wikipedia, the free encyclopedia", the cursor changes as if there's an invisible link.
- Right under the comma, the "link" points to my userpage (it's clickable, and the page will open in the same tab);
- some pixels below, the link will point to [[Help:Page History]];
- going further down, it points to a diff of the sandbox.
There are other points in the page which trigger the links, but the page history one is not easy to spot.
