hasAttribute is not a function

[vcipriani]

We're getting a lot of errors in our application coming from the call to target.hasAttribute('data-ember-action') because hasAttribute is not defined. I haven't been able to identify what event is causing it, but it seems like it is likely something where window is the target.

I'll submit a PR if you want to let me know how you want to guard against this. Seems like changing the line to else if (target && target.hasAttribute && target.hasAttribute('data-ember-action')) would work. I'm assuming there is a reason its a do-while loop and not while, otherwise converting to a while loop should also prevent it.

let handleEvent = this._eventHandlers[event] = (event) => {
      let target = event.target;

      do {
        if (viewRegistry[target.id]) {
          if (viewHandler(target, event) === false) {
            event.preventDefault();
            event.stopPropagation();
            break;
          }
        } else if (target.hasAttribute('data-ember-action')) {
          actionHandler(target, event);
          break;
        }

        target = target.parentNode;
      } while(target && target.nodeType === 1);
    };

Because this package is deprecated and replaced in Ember 3.0, we are no longer receiving the error from this package; however, it is now being generated by Ember's internals.
I've created an issue in ember.js - emberjs/ember.js#16730
