**Overview** There is a workaround to prevent locale's js_alter hook from trying to file_get_contents() the draft JS auto-save URL added in test `ApiLayoutControllerGetTest::testConfigTranslationAvailabilityLinksAndPermissions()` which was added in #3591654 and which also has a @todo to remove this workaround in #3591719 which is closed as a duplicate of #3591729 where the main issue was resolved. Now that the main issue is resolved in #3591729 so we can remove this workaround.
