Pop-outs not working in react 18 with React.StrictMode?

[ryanhamilton]

Describe the bug

WIth React 18 and </React.StrictMode> pop-outs are not visible.
When I click on pop-out, it creates a new window and quickly dissapears. I can click "dock window" but it doesn't reappear.
If I remove </React.StrictMode> pop-outs work as expected.
Some googling seemed to suggest portals may not work the same in strict mode.
