Describe the bug

自定义矩形形状的节点，聚焦节点focusItem的时候没有定位到中心（左右间距不一样）

Your Example Website or App

https://g6.antv.antgroup.com/examples/item/customNode/#card

在https://g6.antv.antgroup.com/examples/item/customNode/#card这里添加聚焦的逻辑： function handleNodeClick(event) { const item = event.item; // animately move the graph to focus on the item. // the second parameter controlls whether move with animation, the third parameter is the animate configuration graph.focusItem(item, true, { easing: 'easeCubic', duration: 500, }); }

// listen to the node click event graph.on('node:click', handleNodeClick);
