Vue 3 component in slot doesn't load

[RoccoDevs]

Current behavior

I have a cypress component test, this test worked before my migration to vue 3. The test added a component through the slots mount option. After migrating to vue 3 that functionality no longer works. Is this expected behaviour? I have included a test project where I try to do the same. Simply open cypress and run the component test.

I have tried various ways of importing the component, like defining the components with names but none seem to work.

The slots get added through mount:

import HelloWorld from '../HelloWorld.vue'
import TheWelcome from '../TheWelcome.vue'

describe('HelloWorld', () => {
  it('playground', () => {
    cy.mount(HelloWorld, {
      props:
        {
          msg: 'Hello Cypress'
        } ,
      slots: {
        default: '<TheWelcome></TheWelcome>'
      }
    })
    cy.get('h1').should('contain', 'Sub component')
  })
})

Desired behavior

Cypress properly adds the vue 3 requirements to load in the component.

You can definitely use "h" function from "vue" package that would let you render this component. I would assume this problem is caused by the absence of runtime template compiler that cannot render the component is slot
