ReferenceError: Hammer is not defined when upgrading from Angular 10 to 11

Hi,

I have just upgraded our Angular Igniteui project from Angular v10.0.14 to v11.2.1 and igniteui from v10.0.6 to v11.0.14

Everything works as expected apart from the Hammer error we are now getting.

The error is raised in every component that has an IgxNavigationDrawerComponent and fails to load the component see attached screen shot.

Thanks.
