// @history        On 08-16-2018 Youtube borked it's layout - added fix
// @history        Fix requires waiting for dom elements removing from this script to avoid having to add external handlers at this time
// @history        Re-added new code to properly fix the 08-16-2018 layout issue (thanks to reddit user pop1040 for posting the code)
