Dynamic component not working on prod mode with Ivy enabled #19321

Hi,
Thank you for your help !

The issue is caused by package @angular/common and @angular/core

Is this a regression?

Yes, it doesn't work with ivy compilation but works with View Engine

Description of the problem:

When creating a dynamic component to load html at runtime, the *ngIf, *ngFor, etc... directives and all components of the commonModule are not loaded whereas we have imported the commonModule in the dynamically loaded module.
Actually, all the imports are ignored.
This happens only in production mode when building in dev mode there is no issue.
Also , it is working with Ivy disabled even in prod mode.

so to summarized

dev mode and ivy enabled : it works
prod mode and ivy enabled : it DOESN'T work

dev mode and ivy disabled: it works
prod mode and ivy disabled: it works
