Help text is tied to a ? icon.
So it only opens if the person mouses over it.
In my personal opinion: I highly doubt that they (the devs) would move it to a tool tip on mouse over on every field as that would be completely obnoxious for some work flows. (Such as all the people that mouse over to click on 5+ fields to say open a ticket.) Also it would really only be helpful to people who do not understand what they are doing. Once they learn what they are doing it would be a waste of resources and traffic.
