I presume there's already a test for it not warning if it's the same component?

@sebmarkbage @gaearon Do we want to land this warning? If so I'll update it |

@ermanzohre Can I ask you to please not “approve” old pull requests? Your actions are creating notification noise for everyone watching the repo. Thanks. |

This warning already exists for class components, but not for functions. It does not apply to render phase updates to the same component, which have special semantics that we do support.

Prevent new data re-render attempts during an existing render to help avoid React 16.13.0's "Cannot update a component from inside the function body of a different component" warning (facebook/react#17099). These changes were originally implemented in apollographql/react-apollo#3930.
