I can't find any element with this ID in the HTML? Can you point me to where it
is defined? Is it being added dynamically? If so, can you add a comment
explaining where the ID comes from?

[Moe, 2016/05/03 20:30:10]

Yes. These are both dynamically added. The comment above the function explains
this.

       this.onImportUserTap_(event);
       event.preventDefault();
+    } else if (element.id == 'sign-in-to-chrome') {

[dpapad, 2016/05/03 17:30:26]

Same here.

[Moe, 2016/05/03 20:30:10]

Same as above.

+      this.browserProxy_.openUrlInLastActiveProfileBrowser(element.href);
