/**
 * Add a keyboard event listener to the Select a Module Type search element.
 *
 * IMPORTANT! This script is meant to be loaded deferred. This means that a. it's non-blocking
 * (the browser can load it whenever) and b. it doesn't need an on DOMContentLoaded event handler
 * because the browser is guaranteed to execute it only after the DOM content has loaded, the
 * whole point of it being deferred.
 *
 * The search box has a keyboard handler that fires every time you press a keyboard button or send
 * a keypress with a touch / virtual keyboard. We then iterate all module type cards and check if
 * the plain text (HTML stripped out) representation of the module title or description partially
 * matches the text you entered in the search box. If it doesn't we add a Bootstrap class to hide
 * the module.
 *
 * This way we limit the displayed modules only to those searched.
 *
 * This feature follows progressive enhancement. The search box is hidden by default and only
 * displayed when this JavaScript here executes. Furthermore, session storage is only used if it
 * is available in the browser. That's a bit of a pain but makes sure things won't break in older
 * browsers.
 *
 * Furthermore and to facilitate the user experience we auto-focus the search element which has a
 * suitable title so that non-sighted users are not startled. This way we address both UX concerns
 * and accessibility.
 *
 * Finally, the search string is saved into session storage on the assumption that the user is
 * probably going to be creating multiple instances of the same module, one after another, as is
 * typical when building a new Joomla! site.
