Since there is no main text on this secondary text, it ended up making the text
display a little lower than center. This allows the text to be vertically
centered correctly.

     <div class="settings-box first two-line">
       <div class="start secondary">

+          on-change="onToggleChange_"

The setting now matches the way the pref is stored, so the |inverted| is not
longer used.

           pref="{{prefs.plugins.always_open_pdf_externally}}">
       </settings-toggle-button>
