Where is the implemenetation in Jira 8.2 instead of find-polyfill.js?


I noticed that find-polyfill.js disappears in Jira 8.2.0.
Is there anyone who know the new implementation of Array.find ?

Documentation Polyfills in Jira says Jira 8.2 uses core-js, but we cannot find the file included core-js.

I want to know the details because of below known problem.

I’m curious why you are interested in the polyfill file itself.
Why does it matter as long as Jira continues to provide polyfill for Array.find?
