What steps will reproduce the problem?
1. Go to google.com and do a search for "amazon smile"
2. Find the result from huffingtonpost.com ("Why Amazon Is Smiling and Charities May Be Losing")
3. Right-click and open in new tab
4. Switch to the new tab

What is the expected result?

Back button stays grayed out, since there's no page to go back to (new tab)


What happens instead of that?

After a few seconds, the back button becomes available. Clicking it takes me to https://www.huffingtonpost.com/?icid=hjx004, a site I never visited.

Inspecting the site, I found this relevant code:


 window.HP.functions.initOnPageLoad = function() {
       window.HP.events.publish("page_loaded"),
       window.HP.functions.resizeFBEmbed(),
       (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPad/i)) && setTimeout(function() {
           0 === i.scrollTop() && window.scrollTo(0, 1)
       }, 250),
       window.HP.params.original_url = window.location.href;
       var e = history.state
         , t = "desktop" === HP.params.device && !!HP.params.entryId && "us" === HP.params.edition.id;
       t && 1 === history.length && history.replaceState ? (history.replaceState({
           reload: !0
       }, "Huffington Post", HP.params.edition.baseURL + "?icid=hjx004"),
       history.pushState(e || {
           reload: !0
       }, document.title, HP.params.original_url)) : history.replaceState(e || {}, "", HP.params.original_url)
   }


I'm unclear what exactly it's trying to do, but it seems like it shouldn't be able to alter history.
