Warnings in testing environment about usage of onBeforeRouteLeave without an active route record

[Sensanaty]

router version 4.2.4, Vue version 3.3.4.

I've got a fairly basic set of unit tests testing a route component. The tests themselves seem to be working just fine, but I do get an error on every single test about my usage of onBeforeRouteLeave in the component, the specific warning being:

[Vue Router warn]: No active route record was found when calling `onBeforeRouteLeave()`. Make sure you call this function inside a component child of <router-view>. Maybe you called it inside of App.vue?

I have my tests set up as described in the docs, like so:

describe('MyComponent.vue', () => {
  let router: Router;

  beforeEach(() => {
    router = createRouter({ history: createWebHistory(), routes }); // routes is my main routes file used in the app
  })

  it('should render', async () => {
    await router.push({ name: 'my-route' });
    await router.isReady();

    component = mount(MyComponent, { global: { plugins: [router] } };
    expect(component.exists()).toBe(true);
  })
}

Any clues on what I'm doing wrong here? The component itself isn't doing anything crazy with the onBeforeRouteLeave(), I just reset some pinia stores, but this functionality is also tested and works fine in the tests, though it also leaves the same warning.

In short, MyComponent should have a <RouterView /> that should be rendering the component that contains the onBeforeRouteLeave(), otherwise it won't register the guard properly
