🤔 [QUESTION]矩形树图，下钻交互的面包屑有没有事件触发的功能？

### 🐛 Question description [Please make everyone to understand it]

### 💻 Link to minimal reproduction

Please provide a link by forking these links [g2plot](https://codesandbox.io/s/g2plot-reproduction-template-gyej1) or GitHub repo. What is a minimal reproduction, and why is it required?

### 🏞 Expected result

### 🚑 Any additional [like screenshots]

* **G2Plot Version**:
* **Platform**:

The issue asks whether the treemap drill-down breadcrumb supports an event trigger, but provides no reproduction or expected result. Start with the linked G2Plot CodeSandbox reproduction template and the treemap interaction documentation or entry point; done means confirming the supported behavior and documenting or specifying the missing event behavior.
