[bug] Object.preventExtensions polyfills every browser

[salemhilal]

Type: Bug report

What

Every browser currently receives the Object.preventExtensions polyfill, even though most modern browsers should support the ES2015 behavior out of the box.

Note that this is a duplicate of an issue on the polyfill-library repo, but it seems like this repo is where issues get tracked.

Details

Polyfill.io URL: https://polyfill.io/v3/polyfill.js?features=Object.preventExtensions
Device: MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports)
Tested browsers and UA's:

• Chrome 75 (Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36)
• Firefox 70.0b5 (Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:70.0) Gecko/20100101 Firefox/70.0)

Additional information

• I ended up finding this issue because I was getting ReferenceError: Type is not defined errors from the same polyfill, which appears to be fixed, but unreleased.
• I'm using a self-hosted but un-modified version of polyfill-service.
