Hello,

What is the setting that controls the font size of the callout that appears in a listing? For example, given a code block like this:

[source,ruby]
----
require 'sinatra' // <1>

get '/hi' do // <2>
  "Hello World!" // <3>
end
----
<1> Library import
<2> URL mapping
<3> HTTP response body

I want to know the setting that will control the size of the callout that appears next to the code as in below:



The conum.font_size property controls the size of callout that appears below the listing (that is not what I want to control):



I am using asciidoctor-pdf and while the size of the second callout is okay, the callout that appear in the listing are extremely tiny!
