This project is a reproduction of an issue with E2E tests in StencilJS. A Github issue related to this was closed a few years ago, but it appears the issue still exists. This project has two components: my-component and my-other-component.
The my-other-component component is a child of my-component. Each component has shadow enabled. The my-other-component component has an h3 in the shadow and the E2E test for my-component component. The E2E test is to check the textContent for the shadow h3. The selector my-component >>> div > my-other-component >>> h3 is used, but only the first shadow DOM appears to be available.
