Issue: [Bug]: Error: Provided component needs to be a string. e.g. component: "my-element"
Labels: question / support,web-components

### Describe the bug

I am using stencilJs (webcomponents) storybook and am upgrading from 6.5 to 7.0. I found an issue someone else also reported over on discord where with webcomponents, in the .stories file importing the component in the meta section is giving the following error 
`Error: Provided component needs to be a string. e.g. component: "my-element"`

<img width="640" alt="Screenshot 2023-07-03 at 5 24 25 PM" src="https://github.com/storybookjs/storybook/assets/106890593/5517148b-db83-4d86-80d1-7f2d4cd4b6c7">

From my understanding, at the time, it was not supported and even in the current docs it seems still 2 years later only using the string 'web-component' is in the docs. However, this is causing an issue in components where we have 20+ attributes as we then must define ALL in args or they do not populate in the controls panel. 

Also wondering, if this is not supported, is the sub-component field also not supported?

Thank you
