when Surface's enableCSSLayout is set to true, Image‘s position is not right

[IvyLady]

`

     <Surface top={0} left={0}  width={size.width} height={size.height} enableCSSLayout={true}>    

        <Image style={this.getImageStyle()} src={iconUrl}/>  

        <Text style={this.getTextStyle()}>Text</Text>    

     </Surface>

`

the right position is at the top border , but I have two boder in the canvas, and the icon is at the secoend

I modify layoutNode.js

`

function walkNode(node, parentLeft, parentTop) {
     node.layer.frame.x = node.layout.left + (parentLeft || 0);
     node.layer.frame.y = node.layout.top + (parentTop || 0);
     node.layer.frame.width = node.layout.width;
     node.layer.frame.height = node.layout.height;

    // add by Ivy
    // because Imagehas two children，the first is layer，the second is RawLayer，
    // and RawLayer（type is image）only keep the parent without adding it self
    if (node.layer.type === 'image') {
         node.layer.frame.x = parentLeft;
        node.layer.frame.y = parentTop;
     }
    if (node.children && node.children.length > 0) {
         node.children.forEach(function (child) {
              walkNode(child, node.layer.frame.x, node.layer.frame.y);
         });
  }

}
