/**
* Loading indicator for search widget
*
* By adding a class on the parent search form
* <div id="simpleSearch" class="search-form__loader"></div>
* A pseudo element is added via ':after' that mimics the appearance
* of the search suggestion and contains the text
* "Loading search suggestions" (message key: vector-search-loader).
*
* After appearing for more than a second, a progress-bar animation appears
* above the loading indicator.
