I had to do a double-take to understand the <if> structure in this file. Could
we if-out the whole first two divs as chromeos-only and change the last div to:

<if expr="chromeos">
  <div class="settings-box">
</if>
<if expr="not chromeos">
  <div class="settings-box row first">
</if>
?

Done.

       <div class="button-strip">
-        <paper-button i18n-content="moreFeaturesLink"
+        <paper-button i18n-content="moreFeaturesLink" class="primary-button"
             on-tap="onMoreFeaturesTap_"></paper-button>
       </div>
