.with_kramdown_ordered_lists_disabled ⇒ Object

 This depends on two internal parts of Kramdown.

  1. Parser registry (kramdown/parser/kramdown.rb#define_parser)

  2. Kramdown list regexes (kramdown/parser/kramdown/list.rb)

 Updating the Kramdown gem therefore also means updating this file to to match Kramdown’s internals.
