给 render 组件设置 ref 无效，会错误的提示有多个 rax 版本，但其实只有一个
ref 必须在组件内部使用么?

To Reproduce

render(
  <div>
    <div ref={() => {}}></div>
  </div>,
  document.getElementById('root'),
  { driver: UniversalDriver }
);
  • Device: Mac
  • OS: Mac
  • Browser chrome
  • Rax Version 1.1.3

不是多个 rax 版本造成的，是给 render 的顶层组件设置 ref 时会提示这个警告，如果在组件内部就不会有问题

我也遇到过相同问题，排查是因为顶层组件在其渲染上下文中没有对应的ownerComponent导致，react确实可以在顶层组件设置ref
