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:

...
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

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