Polymer.dom(event).localTarget returns undefined

[urandom]

Under certain conditions, calling Polymer.dom(event).localTarget returns undefined. I was under the assumption that the property will always be defined, so if that's not the case, please close this issue. The conditions I noticed this in are a bit specific for me, though I think the 'dom-if' element is most likely the cause of it. This is essentially what I have:

<my-custom-scaffold>
<paper-drawer-panel>
   <paper-header-panel drawer>
     ...
  </paper-header-panel>

   <paper-header-panel main>
     <paper-toolbar>
      <template is="dom-if" if="[[ narrow ]]" restamp>
        <content select=".main-title"></content>
      </template>
    </paper-toolbar>
   <div class="content">
       <template is="dom-if" if="[[ !narrow ]]" restamp>
        <content select=".main-title"></content>
      </template>
   </div>
  </paper-header-panel>
</paper-drawer-panel>
</my-custom-scaffold>

<my-custom-scaffold>
   <div class="main-title">
       <paper-icon-button icon="menu" paper-drawer-toggle></paper-icon-button>
   </div>
</my-custom-scaffold>

Essentially the paper-drawer-toggle didn't do anything because the _onTap listener in the drawer-panel did get a valid localTarget.

This is definitely a bug with ShadyDOM.

Thanks for the issue. It has been a great while since this issue was opened. Sadly, this issue misses a live reproduction with Polymer 2 for us to be able to debug and potentially fix. Polymer 2 fixes a large amount of issues, probably including this one as well.

Please see CONTRIBUTING.md for guidelines on filing issues. You can start from this jsBin template as a starting point and link it in the issue template under "Live Demo".

Feel free to file a new issue following these instructions if you can still reproduce this issue with Polymer 2. Thank you!
