react-app-polyfill seems to be unaffected by browserslist

[seansean11]

I was going to create an issue for this, but I figure I should ask first. I am using react-app-polyfill to get IE11 support and following the instructions on the Readme to import both react-app-polyfill/ie11 and react-app-polyfill/stable in that order to the top of my index.js entrypoint. This does give me the ie11 support I need and adds about 37kb to the production bundle size.

Out of curiosity, I started to play with the browserslist to see if using different browser support would change the polyfills from core-js that got bundled, and it didn't. Regardless of the browser support I define it includes what seems to be all of core-js/stable (not even just the ie11 support).

It seems to me that either @babel/preset-env or the implementation of it is broken when used in conjunction with browserslist. I wanted to confirm this suspicion before creating an issue.
