Steps to reproduce

create 3 components:

1. a child component that will be included inside the mixin
2. a mixin
3. a parent component that will use the mixin

when you edit the parent component, the instance of within the template does not receive any coloration or autocomplete, such as for the required value: string prop. In the linked example, the type inference is resolved as:

Component<any, any, any, ComputedOptions, MethodOptions, {}, any>

everything does still compile and executes correctly at runtime, though

What is expected?

components registered inside a mixin should have their definitions recognised in the parent components that import the mixin.

What is actually happening?

the mixin's components are colored like native elements in the parent component's template, and there is no component-specific autocomplete options available. The inferred types for those components' properties are any or generic defaults
