(un)mountComponent seems to behave improperly for the root component of the update

[syranide]

Logging mountComponent and unmountComponent reveals:

MOUNT .0 (WrapperComponent)
MOUNT .0 (MockComponent)
MOUNT .0 (span)
UNMOUNT .0 (span)
UNMOUNT .0 (MockComponent)
MOUNT .0 (MockComponent)
MOUNT .0 (span) 

Which doesn't make sense (to me at least).

var container = document.createElement('div');

var MockComponent = React.createClass({
  render: function() {
    return <span />;
  }
});

var WrapperComponent = React.createClass({
  render: function() {
    return this.props.children || <MockComponent />;
  }
});

React.renderComponent(<WrapperComponent />, container);

React.renderComponent(
  <WrapperComponent><MockComponent /></WrapperComponent>,
  container
);

Can you log the this.type.displayName too and something to distinguish the two renderComponent calls?

Updated, that makes more sense, so the ID being sent is wrong then.
