Attaching a node to document.body freezes the page

[torabiho]

Hi
The component I'm working on is supposed to attach a node to doument.body using createPortal from react-dom and it works perfectly fine outside of playground, but as soon as playgorund tries to run it the entire page freezes and I have to close the tab.

I get this message paused before potential out of memory crash with this line highlighted in the react-dom-server.browser.development.js file:

while (out.length < bytes) {

Thanks for the help :)
