Description

Working with [email protected], I encounter this warning:
Require cycle: node_modules\react-native\Libraries\Network\fetch.js -> node_modules\react-native\Libraries\vendor\core\whatwg-fetch.js -> node_modules\react-native\Libraries\Network\fetch.js
This issue had already kind of been raised in #20841. But it has been closed without being fixed because it seemed to be in the scope of various other libraries.
But the fact is that this particular warning involves react-native code so I'm reopening an issue.

Reproducible Demo

Could not get expo to show any console message.
