This check shouldn't be necessary anymore. Polymer won't fire the observer until
origin is defined.

[Patti Lor, 2017/06/20 08:25:54]

Done.

Because it's the future (Chrome 51+), NodeList has a forEach method that you can
use directly:

this.root.querySelectorAll('site-details-permission').forEach(function(element)
{ ... })

Closure will only like this if you rebase past
https://chromium.googlesource.com/chromium/src/+/9ede2cde5727eecdb377b57b32c5...,
which added in the definition for that method.

Ohh, I was kinda confused about this. Thanks for the FYI :) Rebased & fixed.

JS Style uses camelCase rather than snake_case
