This change gives each shadow root its host before appending its children, and asserts that a root has no children when it's assigned to a host. This ensures the children inherit the correct connectedness. Otherwise, without this change, the user-agent shadow trees for color and file inputs append their children before the shadow root is given a host which, if the input element has already been inserted, means the children stay marked disconnected despite being present in the rendered tree. Disconnected nodes then skip layout invalidations they should trigger. Fixes a crash when submitting a prompt on https://chatgpt.com
