That's "text area" overloaded for you.  From the technical POV of the
display engine, text area indeed does not include the display
margins.  But from the user's POV, I think it surely does, because it
displays the same objects as the text area does: text and images, and
that display is created the same way as you'd display an overlay or
display string in the "text area".
