# For heading that come from template args, core, Parsoid-standalone, and
# Parsoid-integrate different in ther "index" output.
#
# - For templated sections, Parsoid and core differ in some of the metadata.
#   Parsoid doesn't distinguish between sections that come from template args
#   and from templated content - it treats them all as template-generated headings.
#   But core does not consider headings from template-args as "inTemplate", but
#   'fromtitle' is set to false even so.
#
# - Parsoid's behavior is more consistent wrt templates. But, this is potentially
#   a breaking change for users of TOC data. The index for templated
#   content is used to generate section edit links for content coming
#   from a template, and in updating the appropriate article when that
#   section is saved.  So this is potentially a breaking change when
#   Parsoid starts to generate section edit links, and possible one
#   which could cause db corruption.
#
# - Additionally, heading-index is reset in integrated mode because templates are
#   processed by core preprocessor whereas in native preprocessing mode (used by
#   parsertests), the heading index is not reset.
# - See also T222419.

# FIXME:
# 1. This potentially exposes a subtle issue in the interaction between TOC, Cite, and
#    localization. Parsoid doesn't localize numbers in Cite (at all!) since it relies on CSS.
#    But, with the legacy parser, a wiki with localized numbers will have an anchor
#    based off a localized number if a <ref> is used in a heading. Parsoid won't!.
# 2. We probably should be a bit smarter about what to strip for tags when that output
#    comes from extensions. Below, we have stripped all extension typeofs and info.
#    But, depends on who uses this 'line' property and how.

# FIXME: test disabled because CI doesn't have the Cite extension installed
