### Repro steps

1. Clone repro
1. yarn
1. yarn start
1. Open app page
1. open devtools
1. Uncomment the `useEffect` block i.e. add an effect
1. inspect `Component` element
1. comment `useEffect` block i.e. remove the effect
1. Repeat comment/uncomment to see that children grow indefinitely

Might be a duplicate of https://github.com/facebook/react/issues/21436#issuecomment-835406075 since the repro steps are the same. But depending on what the effect is doing, the behavior is different.
