Hey, first of all thanks for a great library! Love it.
I'm using 2.0.0-beta.4 version and there's a utility function that helps filter out children of certain types:

function isComponentOfType(classType, reactElement) {
  return reactElement && reactElement.type === classType;
}

Approach described here #957 with CustomRow injection doesn't work for me in development environment, because all components are proxied by React-hot-loader and strict equality check fails. Is there another way to do it or is it possible to expose an API to change the behavior of isComponentOfType? React-hot-loader is really popular, it would be great to have react-toolbox compatible with it.
