The way it is now, there is no consistency in how books are displayed in the viewer, depending on how the publisher configured their book appearance.
The books HTML is displayed in a sandboxed iframe. This means that it is not possible to directly setup the correspondence that users font size == 1em. Instead the users font size in px is set on the body and html tags. So all other em font sizes work with respect to it. In any case your particular example is fixed in the next beta.
