Links with URLS containing http:// more than once [duplicate]

Question

Possible Link Bug

Sometimes I use the Wayback Machine to link to really good websites that no longer exist. The URLs are of the form http://web.archive.org/web/〈date|*〉/〈url〉, e.g., http://web.archive.org/web/20030606214502/https://superuser.com/index.html. The links display properly in the preview window, but display garbled in the posted answer.

See for example:

Resulting in:
