[Bug] 树状图根据节点属性设置节点边框颜色，粗细等

Version

5.4.3

Link to Minimal Reproduction

https://echarts.apache.org/examples/zh/editor.html?c=tree-vertical

Steps to Reproduce

1.我使用的是自定义的数据，但是数据格式和官网示例的数据结构保持一致； 2.对于其中每一个数据项我设置了一个属性用以自定义节点边框样式，通过设置如下的itemStyle配置项：

...
itemStyle: {  

                        borderColor: function(params){
                            if(params.data.value>10)
                            return "red";
                            else return "green";
                        }

                }
...

3.在我尝试失败之后，我试图打印params，但是并没有任何东西被打印，同时如果我直接在borderColor中return "red"也并没有成功修改样式，这是为什么？为了达成自定义样式的效果我应该如何做？

Current Behavior

渲染树状图节点时自定义修改节点边框样式失效

Expected Behavior

可以根据节点属性值自定义节点边框样式

Environment

- OS:windows 11
- Browser:Chrome 122.0.6261.70
- Framework:React@18.2

**TITLE** [Bug] Treemap sets node border color, thickness, etc. based on node properties **BODY** ### Version 5.4.3 ### Link to Minimal Reproduction https://echarts.apache.org/examples/zh/editor.html?c=tree-vertical ### Steps to Reproduce 1. I use custom data, but the data format is the same as the data structure of the official website example; 2. For each of these data items, I set a property to customize the node border style, by setting the following itemStyle configuration item: ```javascript ... itemStyle: { borderColor: function(params){ if(params.data.value>10) return "red"; else return "green"; } } ... ``` 3. After I tried to print params, but nothing was printed, and if I returned "red" directly in borderColor, I didn't succeed in modifying the style, why? ### Current Behavior When rendering a treemap node, the custom modification of the node border style is invalid ### Expected Behavior You can customize the node border style based on the node property values ### Environment ```markdown - OS:windows 11 - Browser:Chrome 122.0.6261.70 - Framework:React@18.2 ``` ### Any additional comments? _No response_

API says tree.itemStyle.borderColor can be set to a value, not to a function. See #19606 for customizing trees.

Thanks, but according to the demo, it can only customizing tree labels but not the nodes' border or nodes color?
