Data denormalization in Ef Core and Azure Cosmos Db

How do I denormalize data in Ef Core with Azure cosmos db provider?

As shown in this documentation: https://learn.microsoft.com/en-us/azure/cosmos-db/nosql/model-partition-example#v2-introducing-denormalization-to-optimize-read-queries

I need to denormalize an entity which also lives in another container:

```C#
public class Post
{
public int Id { get; set; }
public string Title { get; set; } = null!;
public List Hashtags { get; set; } = new List();
}

public class Comment
{
public int Id { get; set; }
public int PostId { get; set; }
public string Text { get; set; } = null!;
public List Hashtags { get; set; } = new List();
}
public class Hashtag
{
public int Id { get; set; }
public string Title { get; set; } = null!;
public int Puntuation { get; set; }
}
```
So for faster queries I need to embed the Hashtag in the Comment and in the Post (this is just an example, not a real use case), but the hashtag lives in it's own container.

I know this it's not possible in Ef Core due to I'll se an error like this: 'The type 'Hashtag' cannot be marked as owned because a non-owned entity type with the same name already exists.'

Any solution?
