Reproduction link

Steps to reproduce

我这边一个页面外层可以滚动，select设置了getPopupContainer后滚动页面下拉框位置是正常的，但是页面里面还有一个div，div内容超出高度也是可以滚动的，这个div里面同样也有select，给这个select设置getPopupContainer（triggerNode => triggerNode.parentNode）时滚动外层页面是正常的，但是滚动div里面的内容还是会出现下拉框分离

What is expected?

页面内部（页面也可以滚动）的滚动区域里面的select选项不分离

What is actually happening?

页面内部滚动正常，页面内部里面的滚动区域滚动不正常
