Find in {this.props.children}

Hi, I have a problem with a component that uses {this.props.children} in it's render function. All other components within this wrapper won't be found by the "find({key:value})" method.

Start by reproducing the reported behavior in a component whose render function uses this.props.children, then inspect the find({key:value}) method and how it traverses wrapped children. Done means components rendered through this.props.children are found consistently, with a regression check for the reported case.
