"Inspect incoming calls" not finding usages from ascx files?

[5.1.3000]

(ASP.NET MVC)
When using "Find usages" on a controller method that is located in an MVC Asp.Net area, RS finds the ascx page in a "main" view that is calling my controller.
But if I use Inspect->"Incoming Callls", this ascx file is not displayed in the result.

Shouldn't "Inspect->Incoming Calls" return the same result as "Find usages" does?

Thanks.
