Steps to reproduce

Create two custom elements using Vue's defineCustomElement (outer-component and inner-component). In both defineCustomElement calls, use configureApp to provide a value. Then, nest inner-component within outer-component.

What is expected?

I expect that both custom elements get their own isolated injection scope. Values that are provided on inner-component are not visible on outer-component, and vice versa.

Or, even if inner-component has access to the values provided by outer-component, I expect that it definitely has access to the values provided on inner-component and those have precedence.

What is actually happening?

The injection scope of outer-component is applied to inner-component.

This means that when using inject in inner-component, only values that are provided on outer-component can be injected. Values provided on inner-component are not injectable within inner-component.
