What is the expected behavior?

It should push span into .background

Steps to reproduce the problem

Code:

dom
          .newEl("span", {
            class: "star",
            css: {
              left: rand(0, 100) + "vw",
              top: rand(0, 100) + "vh",
              transform: `scale(${rand(0, 150) / 100 + 0.5})`,
            },
          })
          .push(dom.select(".background")).el
          .then((star) => {
            star.addClass("show").then(() => {
              star.addClass("hide").then(() => {
                star.remove();
              }, 1000);
            }, rand(3000, 15000))
          }, 10)
          .then(newStar, rand(100, 2000))

Reproduce: https://stackblitz.com/edit/fastjs-reproduce-jqpuxd?file=src%2Fmain.ts It seems that it only throws an error when giving a FastjsDomList
