Version

3.2.10

Environment

mac、vue3.0 ts、 Chrome120

Reproduction link

https://www.antdv.com/components/tree-select-cn

Steps to reproduce

当文字换行后，虚拟滚动失效。初步猜测初始高度计算错误，不应该按照一行计算。还有可能数据量大，页面还没渲染完毕，默认按照一行计算了，到时虚拟滚动失效。

What is expected?

问题解决，当数据换行后，虚拟滚动不会失效，下拉树可以正常显示

What is actually happening?

TreeSelect 树选择 当文字超出换行，鼠标滚动不了，虚拟滚动失效。问题不稳定，有的浏览器可以。

还有希望不要隐藏滚动条，目前只要滚动才显示滚动条，体验不优化
