 * Hey guys,
 * Unfortunately i can’t share an example link of the issue in action, but here’s
   the console error [https://d.pr/i/yFDT1I](https://d.pr/i/yFDT1I) .
 * What i think it happens, when deferring is enabled, wp-util (underscorejs) is
   not yet ready, but the _.contains call from frontend.js is calling it too early.
 * I would probably suggest creating the WooVariationSwatches on document.ready()?
 * Marius
