Steps to reproduce

1.define 2 props in Vue component，such as "label" for string and "complexProp" for object. 2.import { defineCustomElement } from 'vue', and define custom Elements 3.in native js, setAttribute('label', 'a string value'), at the same time, update another props defined(complexProp) 4.setTimeout wait for the observer, look for the dom property "label" like:

var comp = document.querySelector('my-custom-component');
const test = () => {
  // setAttribute('label'), at the same time, update another props defined
  comp.setAttribute('label', 'update by setAttribute');
  comp.complexProp = {
    content: 'update another props'
  };
  // the label update is not reflected in the component
  setTimeout(() => {
    console.log('setTimeout wait for the observer.');
    console.assert(comp.label === 'update by setAttribute');
  }, 0);
};
onload = () => {
  test();
};
