Can't find variable: _defineProperty on Safari <=15.3 since updating db version >=v1.0.30001561

[jeffprinty]

We are building a production react app (v 16.14.0), bootstrapped with create-react-app, using caniuse via caniuse-lite via browserslist.
We recently did the recommended browserslist update of the caniuse db which caused our bundle to error for users on Safari 15.3. We tried explicitly including Safari 14+ in the browserslist config and rebuilding, this did not solve the issue.

The build works on old Safari with caniuse version 1.0.30001559 ✅
There is an error if built with caniuse version 1.0.30001561 ❌
it also errors (as of 2024-02-29) on the latest version: 1.0.30001591

ReferenceError: Can't find variable: _defineProperty -- index.esm.js - react-dom.production.min.js
ReferenceError: Can't find variable: _defineProperty -- onmessage - scheduler.production.min.js

(the only way I could test was on a very old Mac Mini, but the bundle error is the same as it was on Safari 15.3)

We have solved this temporarily by explicitly specifying version 1.0.30001559 of caniuse in package-lock.json and we will refrain from updating the caniuse db until another workaround is found.

I apologize if this isn't the correct place for this feedback, I wanted to put it out there in case anyone else is experiencing this.
