Do we need to pass in a triggerNode to getPopupContainer in Select

[escapiststupor]

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

In your example repo we don't need to pass anything to getPopupContainer

but the type file says getPopupContainer?: (triggerNode: HTMLElement) => HTMLElement;
What exactly should we pass as triggerNode?

What is expected?

Not sure, maybe getPopupContainer?: () => HTMLElement;

The type should be the same as in RcSelect where getPopupContainer is typed as React.ReactNode | (() => React.ReactNode);

What is actually happening?

You don't have to pass argument to getPopupContainer, the definite works fine: https://codesandbox.io/s/keen-davinci-3o1fu

@afc163 Shouldn't the triggerNode be optional then?
(triggerNode?: HTMLElement) => HTMLElement ?
