Parcel strips core-js import

[danieltroger]

🐛 bug report

When importing certain features from core-js like a polyfill for String.prototype.at, nothing is included in the output bundle.

🎛 Configuration (.babelrc, package.json, cli command)

Please see attached .zip file with reproduction

🤔 Expected Behavior

The imported file is bundled and the polyfill included

😯 Current Behavior

An empty file is emitted

💁 Possible Solution

Don't ignore the side-effects or what's happening and properly bundle the file

🔦 Context

Needed String.prototype.at support but failed in including a polyfill for it

💻 Code Sample

import "core-js/modules/es.string.at-alternative";

Please see example reproduction:

I still think it should work to import from my installed core-js without specifying it in a config file.
