'Open Link in Incognito Window' from DDG also opens a non-incognito tab

[digital-carver]

In the results page of the DuckDuckGo search engine, if I press the command for Open Link in Incognito Window and then the hint chars for any particular result, that result page opens both in an incognito window and in a new non-incognito tab in the current window. (This obviously defeats the purpose of opening it incognito in the first place.)

This doesn't seem to happen on the few other websites that I've tested in (including Google). On DDG, the Open in New Window command too opens a new tab in the current window (in addition to a new Window), but that tab gets closed in a second or two automatically, usually before the page can load. The new tab opened by the Open in Incognito Window command doesn't automatically close though, unfortunately.
