Bug Event.current does not capture Right Click -> Duplicate Event

I have been looking at some code to do with this for a while now. Here is something akin to what I currently have:

Code (CSharp):

1.  
2.  
3. void OnValidate()
4. {
5.     Event e = Event.current;
6.  
7.     if (e != null)
8.     {
9.         if (e.commandName == "Duplicate" || e.commandName == "Paste")
10.         {
11.             ///Do Stuff
12.         }
13.     }
14. }
15.  

It works perfectly when I use the keyboard to either duplicate or copy-paste an object and drag and drop from the project view and even when I go into the Edit -> Duplicate / Copy / Paste commands.

The problem is, I noticed when I right-click on the object in the hierarchy and then click on duplicate or copy / paste that it does not trigger these events or even the OnValidate code?

Wondering if this is definitely a bug?
