UDA on double nested struct

[Sebastiaan Koppe]

Hey, I am trying to get UDAs from a doubly nested struct, to no 
avail:

code
---
import std.traits : hasUDA;
enum hover;

struct Style {
   struct Root {
     auto margin = "10px";
     auto backgroundColor = "white";
     @hover struct Hover {
       auto backgroundColor = "gray";
     }
   }
}
pragma(msg, hasUDA!(Style.Root.Hover, hover));
---

returns false. Bug or no? (Yes, I am generating css at compile 
time.)

Putting it on Root or on Style works as intended;
