Here's a test case quickly:
http://sirisian.com/javascript/dom3mouse.html
source:
<!doctype html>
<html lang="en">
<head>
<title>Dom 3 Mouse</title>
<script type="text/javascript">
"use strict";

window.onload = function()
{
    var target = document.getElementById("region");
    target.addEventListener("mousedown", function(e)
    {
        e.preventDefault();
    }, false);
    target.addEventListener("mouseup", function(e)
    {
        e.preventDefault();
    }, false);
};
</script>
</head>
<body style="margin: 0;padding: 0;">
    <div id="region" style="width:2000px; height:2000px; background-color:#f0f;"></div>
</body>
</html>

The mousedown for the middle mouse works flawlessly. e.preventDefault stops the middle mouse pan from starting. The right click does not. So the fix that needs to be implemented for the mouseup is that if javascript calls e.preventDefault() then don't execute the default action of creating a context menu.
