Ragnor: It kinda looks like a weird interaction between Chrome and Linksmart to me from a quick look in the Chrome dev tools, haven't tested with addon's disabled though.

Yep, Linksmart is doing it. 

I've just tested with the Ars badbios link earlier in the thread and you can see that Linksmart adds a mousedown handler on the link. 

It ignores right clicks (button == 2) but doesn't ignore middle clicks (button == 1):

F = function(a, c, n) {
    a = a || window.event;
    if (2 == a.button || c.getAttribute("data-ls-clicked"))
    return !0;


So then it eventually ends up setting the location of the current tab:

 window.location = c.href
