# These filters transform GitLab Flavored Markdown (GFM) to HTML.
# The nodes and marks referenced in app/assets/javascripts/behaviors/markdown/editor_extensions.js
# consequently transform that same HTML to GFM to be copied to the clipboard.
# Every filter that generates HTML from GFM should have a node or mark in
# app/assets/javascripts/behaviors/markdown/editor_extensions.js.
# The GFM-to-HTML-to-GFM cycle is tested in spec/features/copy_as_gfm_spec.rb.
