title: Browser support for stopImmediatePropagation?
body: <p>IE support for <code>stopPropagation()</code> is lacking, and <a href="https://stackoverflow.com/a/387750/165673">requires workarounds</a>, but I can't tell if the same thing is true for <code>stopImmediatePropagation()</code>- is it safe for all browsers, or does it requires its own set of workarounds?</p>
