<!-- FIXME(polymer-modulizer):
These imperative modules that innerHTML your HTML are
a hacky way to be sure that any mixins in included style
modules are ready before any elements that reference them are
instantiated, otherwise the CSS @apply mixin polyfill won't be
able to expand the underlying CSS custom properties.
See: https://github.com/Polymer/polymer-modulizer/issues/154
