Javascript errors after upgrade to 9.4.1

After upgrading to 9.4.1 (commit: 6678b4e5) I'm getting javascript errors as if the bundle was incorrectly minified.

I tried to purge all modules and assets before compiling:

sudo -u git -H bundle exec rake gitlab:assets:purge_modules yarn:install gitlab:assets:purge gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production

But the error remains.
