 * The run-start focus decision `ComposerPrimitive.Input` makes, for other
 * composer implementations (`@assistant-ui/react-lexical`) that have to make the
 * same call. The thread root comes from context, so a composer portaled outside
 * `ThreadPrimitive.Root` still knows which thread it belongs to; reading the
 * `data-aui-thread-root` attribute instead concludes that focus is elsewhere and
 * leaves the keyboard where the thread put it.
 *
 * Returns `false` for a missing element, and for the element itself already
 * holding focus.
