componentDidMount fires before child component is attached to DOM about preact HOT 7 CLOSED

Yup, on my to-do list. thx.

Interesting. Debugger shows it's attached to the parentNode from <App>, but <App> hasn't yet been appended to the DOM itself. I'd love to avoid deferring componentDidMount(), since that would cost a traversal during render, but that might be the only way. Are you sure React only calls this hook once the whole tree is mounted?

Maybe just a straight up queue would be okay here. It only happens at the root (because render() is special-cased).

Looks like React only calls the hook once the element is mounted: https://jsfiddle.net/x6xpdkjL/

The docs seem to confirm: https://facebook.github.io/react/docs/component-specs.html#mounting-componentdidmount
