Infinite scroll bug about shoes3 HOT 2 OPEN

The proper testing script for Shoes 3.2 is:

Shoes.app do
  stack :bottom => 0 do
    para "I'm a footnote of sorts.", :align => "right"
  end
end

The initial script provided by @zzak at https://gist.github.com/66b6ef92d5f355fe0eb3 causes the following error:

Error in <unknown> line 0 | 2015-01-22 04:05:04 -0500

(Small update) This bug is still present in Shoes 3.3.2.
