Configuring originalTitle & originalDesc through index.html

<input type="hidden" id="original_title" value="true">
<input type="hidden" id="original_desc" value="true">

PreText UI has high precedence over facet.js configuration for display settings of originalTitle & originalDesc. Instead of editing facet.js, you can consider updating the settings in the index.html file.
