Not applicable.

I've been messing around with this for a couple of days at this point and feel a bit silly. See this issue [here](https://github.com/facebook/react-native/issues/13522). This would have saved me some time and will likely save others time as well.

Thank you for taking the time to look over this PR. Cheers!
Closes https://github.com/facebook/react-native/pull/13524
