When in the visual editor, it is possible to load links in a new tab/window by ctrl+clicking on the link.
For section links and red links the URL this loads is wrong.
Red links lead to: https://en.wikipedia.org/w/<page> e.g. https://en.wikipedia.org/w/This%20Is%20A%20Guaranteed%20Red%20Link
Section links lead to: https://en.wikipedia.org/<page#section> e.g. https://en.wikipedia.org/London#History (i.e. /wiki/ is missing from the URI). After a few seconds this redirects to the correct article but ignores the section.
