I forked and cloned the repo this morning (at c88fb49d37fd01024e0a254a37b7810d107bdd1d), ran `yarn` and `yarn test`, and several tests failed.

React version: main (c88fb49d37fd01024e0a254a37b7810d107bdd1d)

## Steps To Reproduce

1. Clone repo
2. `yarn` and `yarn test`

I was on the latest NodeJS version (16.10.0). Note that tests pass for me when switching to the 14.x LTS release of Node.

## The current behavior

13 tests fail across 5 suites. Output at https://gist.github.com/josephsavona/91a3d48add8a1c47c71178522583281b

## The expected behavior

All tests pass
