This is somewhat related to bug 50321. Steps to reproduce: 1. Open your own sandbox/userpage (not a page in the mainspace) in VisualEditor. 2. Add a link to a word ("xxx"). 3. Control-click/right-click/command-click the new link to open the link in a new tab or new window. 4. Discover that VisualEditor has sent you to an invalid URL: http://en.wikipedia.org/w/Xxx or http://en.wikipedia.org/wiki/User:Whatamidoing_(WMF)/Xxx
This is bug 48915 although the bug title "VisualEditor: Respect Parsoid's <base>" describes the solution not the effect so I'm not surprised you didn't find it. *** This bug has been marked as a duplicate of bug 48915 ***
