It's a jQuery usage issue. Your code is adding new event listeners each time the user clicks resulting in animations triggered multiple times. Move the code below outside of the click handler so it runs only once per animationcomplete__fadein event.
$(loading_sky).on("animationcomplete__fadein",()=>{
console.log("fadeincompleted");
el.setAttribute("color","#"+(Math.floor(100000 + Math. random() * 900000) ).toString());
$.each(scene,(i,e)=>{ e.emit("fadein"); });
setTimeout(()=>{loading_sky.emit("loadfadeout")},1100)});
});
