Bug
What is the current behavior?
App crashes
If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
This is currently my only component, copied from the docs
import React, { useState, useEffect } from 'react';
function Example() {
const [count, setCount] = useState(0);
// Similar to componentDidMount and componentDidUpdate:
useEffect(() => {
// Update the document title using the browser API
document.title = `You clicked ${count} times`;
});
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>Click me</button>
</div>
);
}
export default Example;
However, my page crashes, and I get the following error
Uncaught TypeError: Cannot read property 'expirationTime' of undefined

Unfortunately, I cannot reproduce it in codesandbox, so not sure what exactly I might be doing wrong?
What is the expected behavior?
Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
16.8.0 (React & ReactDOM)
