Steps to reproduce

export interface BlogContent {
    id: string;
    title: string;
    contentMd: string;
    typeId: string;
    userId: string;
}
  const blogContent = ref<BlogContent>();

What is expected?

i would like to get the blogContent'type is only 'Ref< BlogContent>', but it is not

What is actually happening?

blogContent'type is "const blogContent: Ref<BlogContent | undefined>" and i will get the mistake is "Object is possibly 'undefined'.Vetur(2532)"

You are saying it's aways an object but initializing it with an undefined value, that's just wrong code.
