Bug: Can't bind to 'property' of a third-party standalone component

[kkoo95]

Description of the bug

I have a standalone component which imports a standalone component from a third-party lib. And when i run my tests fairly simply with MockBuilder, i get warnings/errors in the console like:

NG0303: Can't bind to 'property' since it isn't a known property of 'ext-component' (used in the 'MyTestedComponent' component template).

An example of the bug

import { ExtComponent } from '@org/lib';
import { Component } from '@angular/core';

@Component({
    selector: 'my-component',
    standalone: true,
    imports: [ExtComponent],
    template: `<ext-component [property]="42" /> `
})
export class MyTestedComponent {}

describe('MyTestedComponent', () => {
    beforeEach(() => MockBuilder(MyTestedComponent));

    it('should create', () => {
        expect(MockRender(MyTestedComponent)).toBeDefined();
    });
});
