ngx-echarts test teardown bug

ngx-echarts.spec.ts

import { Component } from '@angular/core';
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import * as echarts from 'echarts';
import { NgxEchartsDirective, NgxEchartsModule } from 'ngx-echarts';

@Component({
    template: '<div echarts [options]="options"></div>'
})
class TestHostComponent {

    options?: echarts.EChartsOption;
}

describe('echarts integration', () => {
    let component: TestHostComponent;
    let fixture: ComponentFixture<TestHostComponent>;

    beforeEach(async () => {
        await TestBed.configureTestingModule({
            imports: [
                NgxEchartsModule.forRoot({ echarts })
            ],
            declarations: [
                TestHostComponent
            ]
        }).compileComponents();

        fixture = TestBed.createComponent(TestHostComponent);
        component = fixture.componentInstance;

        fixture.detectChanges();
    });

    it('should change the options', () => {
        const echarts = fixture.debugElement.query(By.directive(NgxEchartsDirective)).injector.get(NgxEchartsDirective);
        component.options = {
            series: [
                {
                    type: 'gauge',
                    data: [{ value: 0.3 }]
                }
            ]
        };

        fixture.detectChanges();

        expect(echarts.options).toBe(component.options);
    });
});

Hi @homj,

I can't reproduce the error when test it with Jest or Karma. Both of the tests are passed.

Error: 1 component threw errors during cleanup

Do I miss anything?
