Harness is attempting to use a fixture that has already been destroyed

I have a trivial unit test that passes but throws the error, "Harness is attempting to use a fixture that has already been destroyed" when I run ng test --watch=false. Is this happening because I'm placing my component in <ng-template>? Does anyone know how to resolve this error?

MenuComponent Spec

describe("MenuComponent", () => {
    let testHostFixture: ComponentFixture<TestHostComponent>;
    let myMenuHarness: MenuHarness;

    beforeEach(
        waitForAsync(() => {
            TestBed.configureTestingModule({
                declarations: [...],
                imports: [...],
                providers: [...],
            }).compileComponents();
        })
    );

    beforeEach(async () => {
        testHostFixture = TestBed.createComponent(TestHostComponent);
        myMenuHarness = await TestbedHarnessEnvironment.harnessForFixture(
            testHostFixture,
            MenuHarness
        );
        testHostFixture.detectChanges();
    });

    describe("simple test", () => {
        it("should pass", async () => {
            await myMenuHarness.openMenu();
            expect(true);
        });
    });

    @Component({
        selector: `my-test-host-component`,
        template: `<kendo-grid ...>
            <ng-template kendoGridColumnMenuTemplate let-service="service">
                <app-my-menu [service]="service"></app-my-menu>
            </ng-template>
            <kendo-grid-column ... ></kendo-grid-column>
        </kendo-grid>`,
    })
    class TestHostComponent {
        @ViewChild(MenuComponent)
        public menu?: MenuComponent;
    }
});

MenuHarness

public async openColumnMenu() {
    const element = await this.queryColumnMenuButton();
    element?.click();
}
