Does this really work? You do rendering in a callback block. This
doesn't make sense.

html is the rendering context on which you render. If you come from a
Java background this is very much like the #paintComponent(Graphics)
method. You can store it in an instance variable at the beginning of
#renderContentOn: instead of passing it around to every render method,
but this in general not done.

Probably because there's not instance variable referncing the rendering context.
