After updating to the latest version of react testing library, I am seeing TS failures unfortunately

Type 'JSXElementConstructor<{ children: ReactElement<any, string | JSXElementConstructor<any>>; }>' is not  assignable to type 'JSXElementConstructor<{ children: ReactNode; }> | undefined'.

Changing ReactElement to ReactNode seems like a breaking change, any help?

We see failures with this message now:

Type '({ children }: { children: JSX.Element; }) => JSX.Element' is not assignable to type 'JSXElementConstructor<{ children: ReactNode; }> | undefined'.

Missing breaking change? Broke our tests.
