onConsole triggering for handled commands

"Note: The event will not be triggered if the message can be processed by an existing command handler"

  
function inputConsole ( text ) 
    if ( getElementType ( source ) == "player" ) then 
        --Typed by a Player 
        outputChatBox("Player C: "..text, getRootElement()) 
    else 
        --Typed by the Server Console 
        outputChatBox("Server C: "..text, getRootElement()) 
    end 
end 
addEventHandler ( "onConsole", getRootElement(), inputConsole ) 
  

When I first created this code it worked flawlessly, the event only triggered for non-handled(non-existent) commands. But after sometime (refreshing resources, restarting the server etc), now the events triggers even for handled commands. Is it a bug? or am I missing something?

Or maybe I imagined it and it triggered for handled commands since the start.
