BUG: update listener triggered on initial load

Hello! I found weird bug with update listener. It's triggered on initial load if html code has <img> tag with class attribute:

const editor = grapesjs.init({
  container: "#gjs",
  storageManager: { type: 0 },
  plugins: [],
  components: `
    <img src="https://images.unsplash.com/photo-1602536062611-8996fd6f8149?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=1998&q=80" alt="Some alt text" class="centered"/>
  `
});

editor.on("update", () => {
  console.log("udpdated");
});
