A note on why we can't just do initialVNode.el = placeholder.el:

In component's render effect on initial mount, we use the presence of el to serve as a check for adopted server-rendered DOM. If el is present, it will perform hydration instead of client mount. This is why the previous fix broke Nuxt in ecosystem-ci.
