Post to Contained Entity Collection fails

Assemblies affected
Microsoft.AspNetCore.OData 8.0.11

Describe the bug
https://github.com/lboss75/issue24867.git

I have simple model with contained entity collection:
public class Project
{
..
public virtual IList Modules { get; set; }
}
...
(https://github.com/lboss75/issue24867/blob/main/WebApi/Model/ODataModel.cs)
builder.EntityType().HasMany(x => x.Modules).Contained();

And controller method to post new items into contained collection (https://github.com/lboss75/issue24867/blob/main/WebApi/Controllers/ProjectsController.cs):
public async Task PostToModules([FromODataUri] int key, [FromBody] Module value)

But when I try to call this method I got error:
'The entity type 'WebApi.Module' is not compatible with the base type 'WebApi.Project' of the provided entity set 'Projects'. When an entity type is specified for an OData resource set or resource reader, it has to be the same or a subtype of the base type of the specified entity set.'

I was able to get OData to switch context and accept my parameter only if I write:
builder.EntityType().CollectionProperty(x => x.Modules);
But in this case the type 'WebApi.Module' forced be complex type.
