**report a *bug*?**

**What is the current behavior?**

onToggle prop attached to a details html element does not attach the event handler , instead shows a warning "Warning: Unknown prop `onToggle` on `<details>` tag. Remove this prop from the element. For details, see https://fb.me/react-unknown-prop
    in details (created by Details) ...

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/reactjs/69z2wepo/).**

WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)

   * @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html
   *
   * Also, `keyup`/`keypress`/`keydown` do not bubble to the window on IE, but
   * they bubble to document.

   * @param {string} registrationName Name of listener (e.g. `onClick`).
   * @param {object} contentDocumentHandle Document which owns the container
