why does it take two steps to get the proper listing for a person?

This has been driving me insane since it started, because it's so weirdly non-intuitive that I can't think why anyone on earth would choose this. When you go to a person's imdb page, at the top it lists all the things they do - director, actor, producer, etc. Since it almost invariably has the wrong thing as the default (i.e. Tom Hanks as producer) the first thing you do is click on what you want to see (i.e. actor). But instead of then displaying acting credits, it weirdly shifts "actor" further to the right, the opposite direction from what you want, and you have to click a second time to get it to list what you want to see at the top. So, 2 questions 1) Is there any way to change this behavior? 2) WTF? What are they thinking? What is the thought process behind this? What purpose does it serve? Does anyone know?
