### Repro steps

1. Wrap something into `<Fragment key="stuff">`
2. It doesn't show up in DevTools

We filter out fragments because they tend to be useless. But this one is important! Keys are crucial and we should show anything with a key in the tree.

   This function is copied from React and should be kept in sync:
   https:github.com/facebook/react/blob/main/packages/react-reconciler/src/ReactFiberTreeReflection.js
   It would be nice if we updated React to inject this function directly (vs just indirectly via findDOMNode).
