You should use a different way for wait subtitle.

Lines 101 to 104 in fa9afe5

    
             subtitleWrapper.addEventListener("mouseleave", () => { 
        
               video.play(); 
        
             }); 
        
           }, 3000);

Fixed

	subtitleWrapper.addEventListener("mouseleave", () => {
	video.play();
	});
	}, 3000);
