Mount node on Portal components crashes when specified node inside the current component

See original GitHub issue

In the sandbox https://codesandbox.io/s/ly54m63vz7, there is a reproduction case and a hack to fix if encountered. The clean fix would be to use a function getMountNode ~~instead of~~ as well as mountNode for these use cases. Note that this API is used (getPopupContainer) in https://github.com/react-component/trigger and in Ant Design components

Steps

Set mountNode of a Portal component to its parent

Expected Result

the portal should mount on the specified mountNode

Actual Result

Crashes Cannot read property 'appendChild' of null

Version

0.75.1
