Hi,
$animate.on generates a javascript error with IE11.
All is ok with Chrome and Firefox.
Plunker here (to test with IE):

Open Developer Tools with F12 and click on "Visible".
The error is:
TypeError: L’objet ne gère pas la propriété ou la méthode "contains"
at Anonymous function (https://code.angularjs.org/1.4.8/angular-animate.js:2146:11)

In line 2146 in angular-animate.js (v1.4.8), there is:

function findCallbacks(parent, element, event) {
    ...
    forEach(entries, function(entry) {
          if (entry.node.contains(targetNode)) {
            matches.push(entry.callback);

IMHO, this is a problem with method "contains" with IE.
Node.contains is not implemented on Node.
See:

But, I haven't found a patch or a workaround for this bug.
