ESM output missing regeneratorRuntime declaration

[binh-dam-ibigroup]

When using ESM Modules as of core-utils 3.2.1, async methods are transpiled into code that refers to regeneratorRuntime, however an import/require of regeneratorRuntime is missing somehow. The missing import is causing the UI to crash when it invokes async from the core-utils package, for instance.
