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.
