Random timeouts printed in console

[cristianoccazinsp]

After rendering a component with <Recaptcha ... and the page unmounts including the component, for some reason the following is printed in the console:

Looks like this started happening since React v18

I'm finding this too on 17.0.2

Turns out, this happens if the component unmounts shortly after mounting (probably before the captcha renders). I had a slight bug in my application where the component would render on construction and disappear instantly due to a componentDidMount update changing the conditional logic to render it. After fixing that, the issue went away.

Yep, that's it. I was conditionally removing the component from the page after theverifyCallback, which triggered the timeouts. I've changed the component to use visibility: hidden for now. However, removing the component probably shouldn't throw these console errors?
