HTML
<p id="console"></p>
<p>When I follow this link, the behaviour of the sessionStorage is not always the same:</p>
<p>
1. mouse-left-click
<br />-> the sessionStorage <b>is copied</b> to the Target Site
<br />2. mouse-right-click, then select the menu option "Open Link in new Tab"
<br />-> the sessionStorage <b>is empty</b> on the Target Site.
<br />
</p>

var value = (new Date()).getTime();
sessionStorage.setItem("test", value);
$("#console").html("SessionStorage item set: " + value);
