我必须使用 vis js 网络将标签与节点内的一个字母（数字）对齐。正如文档所说，选项内部有font.align属性node，默认情况下它设置为center. 标签中有多个字母时看起来不错：
但是，对于一个字母，标签看起来像左对齐：
这是一个错误还是我做错了什么？如果它是一个错误，我该如何解决它？
我的完整代码（我正在使用 react-graph-vis 1.0.5 版）：
import React from 'react';
import Graph from "react-graph-vis";
import 'vis-network/styles/vis-network.min.css';
const ExecutionPathGraph = ({issueTraces}) => {
const graph = {

{ id: 1, label: "1"},
{ id: 2, label: "2"},
{ id: 3, label: "3"},
{ id: 4, label: "4"},
{ id: 5, label: "5"}
],
edges: [
{ from: 1, to: 2 },
{ from: 1, to: 3 },
{ from: 2, to: 4 },
{ from: 2, to: 5 }
]
};
const options = {
