Error raised in _onTap function for removed elements actioned by tap events

[ArthurJahn]

When removing a child element from a drawer, the following error raised:

Uncaught TypeError: targetElement.hasAttribute is not a function


just added one more condition to if clause in line 502 so it doesn't happened anymore.

_onTap: function(event) {
        var targetElement = Polymer.dom(event).localTarget;
        var isTargetToggleElement = targetElement &&
          this.drawerToggleAttribute && targetElement.hasAttribute &&
          targetElement.hasAttribute(this.drawerToggleAttribute);

        if (isTargetToggleElement) {
          this.togglePanel();
        }
      },

It's a minor issue, maybe caused by a bubbling event after element has been removed, but you should look into this.

hmm. so what is targetElement if it's not an element with hasAttribute? Would you mind sending a code that reproduces this issue?

[ArthurJahn]

when the element is dynamically removed from dom, the object received in this function is window, that does not provide a method hasAttribute.
I'll send you a code to reproduce this issue.

cc @azakus. Is it possible for Polymer.dom(event).localTarget to return window in the case described above?

friendly ping @azakus

Any news for this bug?

We can see this bug in polymer-element-catalog project.
For example, in this page:
https://elements.polymer-project.org/browse?tag=live&view=cards

When we click on a tag (for example "live") we has this error:
"TypeError: Argument 1 of Node.contains does not implement interface Node."
