OData query option $count in $expand not working

Question

I tried to use $count in an $expand like this query

.../OData/Foo(1)?$expand=Bars($count=true)

However count is no where to be found in the result.

{
  "...": "...",
  "Bars": {
    "...": "..."
  }
}

No error either. I'm using ASP.NET Web API OData 5.4, which is using OData v4.

What gives? Not implemented yet?
