Invalid type: 'container' Error when new window using ReactDOM.createPortal

[Jenny-YJ]

Hi, please help

I want to use the React - Potals feature to map new windows

The main window is loaded well, but the window with the potals function occurs an error that

Invalid type: 'container' must be a String or HTMLElement.

I guess, when creating mapboxgl by new , the container is found in the document of the main window.
But the container is in the new window (the portals is used).

I've also tried out other maps, including 'MapGL' and 'StaticMap', but all have been error in the same place.

In the case of deck.gl, both of them work well.

here test source..

codesandbox

Is there any way to deliver the handle of the new window, or what other way?
