为什么向图形样式 sheet 添加新属性在 Neo4j 中不起作用?

Why does adding new properties to the graph style sheet not work in Neo4j?

Neo4j Browser User Interface says that I can run :style, export it, modify it and drag it back to change the style. I try changing the default border width, and adding two new properties for nodes: text-align and shape, as explained in Graph Stylesheets 的开发者指南:

node {
  diameter: 50px;
  color: #A5ABB6;
  border-color: #9AA1AC;
  border-width: 10px;
  text-color-internal: #FFFFFF;
  font-size: 10px;
  text-align: "below";
  shape: regtangle;
}

但只有边框宽度发生变化。为什么其余的不起作用?

text-alignshape 似乎不是 Neo4j 浏览器支持的属性。
styling guide in the browser manual 列出八个属性。
并且根据这个列表,似乎只有文本的颜色是可以自定义的。
