Steps to reproduce

Not needed

What is expected?

I'm not sure if this is a bug.
When I use defineCustomElement to convert a Vue Component to a Web Component,Import another component into a Vue component, and the style of the other component will not be injected into the shadow root of the custom element.

What is actually happening?

The 2 components of Vue are used as a web component (at least it appears to be in a shadow root), and the styles should be injected into the shadow root
