If you can - edit script to update style var as below:
style.innerHTML = '.ytp-autohide .ytp-chrome-bottom{opacity:1!important;width:100%!important;left:0!important;display:block!important}.ytp-autohide .ytp-chrome-bottom .ytp-progress-bar-container{bottom:-1px!important}.ytp-autohide .ytp-chrome-bottom .ytp-chrome-controls{opacity:0!important}';
