 In [changeset:"57981" 57981]:
 {{{
 #!CommitTicketReference repository="" revision="57981"
 Script Loader: stop enqueueing some now obsolete polyfills.

 Stop enqueueing polyfills such as `wp-polyfill-inert` (for the `inert`
 attribute) and `regenerator-runtime` (for generator functions), as they
 are no longer needed, considering the WordPress project's
 [https://make.wordpress.org/core/handbook/best-practices/browser-support/
 browser support policy].

 In addition to that, `wp-polyfill` (essentially `core-js`) is no longer
 enqueued as a dependency of `react`. This was added in [43903] to ensure
 compatibility with IE 11, which is no longer supported by WordPress.
 Developers requiring `wp-polyfill` need to manually add it as a dependency
 for their scripts.

 Props swissspidy, flixos90, adamsilverstein, youknowriad, gziolo.
 Fixes #60962.
