Research direction

Start by reproducing the example with Component({ options: { virtualHost: true } }), simulate.load, simulate.render, and querySelector('.son'). Read the component simulation and rendering paths involved in that reproduction, then add or update a unit test so the virtual-host child can be queried after attach and the test passes.

Description

// child.js
Component({
  options: {
    virtualHost: true,
  }
})

const id = simulate.load({
  template: `<child class="son" />`,
})
const comp = simulate.render(id);
comp.attach(document.createElement('parent-wrapper'));
const $search = comp.querySelector('.son'); // undefined
