mdMenu: menu not closing on firefox 39 and chrome

[KReden]

Reference Issue: #3438

This was reported as fixed in master several days ago but as of right now on FF and chrome it is broken again.

When the menu opens it seems to kill all input for the page. A refresh is needed to recover

@KReden - I am unable to reproduce this with the latest code in master:
https://material.angularjs.org/HEAD/#/demo/material.components.menu.

FF and Chrome both open and close as expected.

@ThomasBurleson I updated to 0.10.1-rc3 and I am still getting this bug. I thought it might be something on my end interfering with how mdMenu worked but I can get it to happen on the Angular Material website as well. While trouble shooting I noticed that when the bug happens md-clickable is not applied to the div containing the menu. See screenshots below:

This also applies to android:

@KReden see #3899

It fixes the issue but won't be committed since there's a new animation system being written.
