bug(icon): Error retrieving icon gk:bike! Cannot assign to read only property 'taskId' of object '[object Object]'

[GeorgeKnap]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

18

Description

After migrating from material 18 to 19 I'm getting runtime error on all of my svg icons.

my icons are registered in MatIconsRegistry like this

matIconRegistry.addSvgIconInNamespace(
        'gk',
        'bike',
        domSanitizer.bypassSecurityTrustResourceUrl('assets/img/bike.svg')
      );

provided via app initializer:

provideAppInitializer(() => registerSvgIcons(inject(MatIconRegistry), inject(DomSanitizer))),

and used in component

<mat-icon svgIcon="gk:bike"></mat-icon>

I run all the automatic migrations and I'm not aware any breaking changes here.
