mdMenu: invalid comparison in menu-iterim-element.js

[Frank3K]

In menu-interim-element.js there is an invalid comparison in the onclick-handler of the menuContentEl. Line #157 (058efeb) contains the following check:

 do {
    if (target && target.hasAttribute('ng-click')) {
      ...
    }
  } while ((target = target.parentNode) && target != opts.menuContentEl)

target is here a native DOM element, whereas opts.menuContentEl is a jqLite object. Therefore the comparison is always true. This can lead to an error since target can now become (in given conditions) equal to document, which does not have a hasAttribute method.

Furthermore, this loop lacks support for data-ng-click and x-ng-click.

I see this is also reported as #3258.
