I wonder if the label bug is correct here, as this is not a bug, or? The warning message appears as intended.

This is a question for a JavaScript expert.

“bug” is the correct label until an expert qualifies the issue and says it can be dismissed or the issue has been addressed. The Open Source Team has so far not responded.

In the meantime the npm run build reports that eventregistration.js has grown even further in size

WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
Assets:
  eventregistration.js (993 KiB)

and that there is a problem additionally with cwaa.js
