self should be a getter

But now it's a usual property.

Is there a specific issue this is causing for you?

[zloirock]

@kitsonk sure, and it will cause problems for thousands of users.

self now is a part of Minimum Common Web Platform API. I wanted to add a proper polyfill of this (not just globalThis.self ??= globalThis) to core-js. This polyfill contains a proper descriptor detection and in case of incorrect descriptor overwrites incorrect implementation - like Deno. Babel and SWC inject core-js polyfills for unsupported features - by the core-js compat data - and for bundling / loading it's an extra couple of KB.

Yup, thanks, that makes a lot of sense.
