Bug Description

In React project using v7 and height="auto", "ResizeObserver loop completed with undelivered notifications." error is displayed in Chrome dev console.

The codesandbox.io demo shows the error in the built-in console. It seems to happen about half the time, clicking "refresh" a few times should show the error.
