gForce布局下拖动节点后想通过其他事件固定节点，节点会偏移 #4461

Describe the bug

官网的demo 在gForce布局下拖动节点后固定没有问题，但是想通过其他事件固定节点，节点会产生偏移，我在想使用的鼠标右键点击固定，

Steps to Reproduce the Bug or Issue

1、使用官方demo https://g6.antv.antgroup.com/zh/examples/net/forceDirected#gForceFix 2、原先的refreshDragedNodePosition函数改为 refreshDragedNodePosition(e) { const model = e.item.get('model'); model.x = e.x; model.y = e.y; } 为了方便查看 我把nodeStrength改为了800，nodesize：40 2、在原有的代码上添加右键点击固定的逻辑 graph.on('node:contextmenu', function (e) { const model = e.item.get('model'); model.fx = e.x; model.fy = e.y; graph.layout() });

Expected behavior

右键点击后节点固定不偏移
