#onstart

A scene-authored component cannot resolve, inside its own OnStart, a component that another component creates inside that other component's OnStart. Authored beside is not authored before, so the binder looks up the target before it exists, gets null, and holds that null for the whole session behind one warning line. The whole feature does nothing while every part it depends on works. Bind lazily instead: retry the lookup on a short interval until the target resolves, and warn once if it never does.
