  /*
   * TL;DR => Safari Select Box onchange Event Bug Fix
   * Problem:
      On keyboard event of select box (like searching for desired options),
      safari doesn't fire the event even hitting enter key. Instead, it fires
      the change event on again hitting enter key or clicking anywhere,
      so as we can get the selected option's value. Same happen when clicking
      on desired option. This is weird.
