Description

From T355092#9483046, Parsoid needs to handle sections defined in HTML-returning components (ex: special page transclusions, parser functions returning html) just like it deals with extensions. T355092 only dealt with extensions.

This is an edge case, but needs to be handled.

ABreault-WMF added a subscriber: ihurbain.

In T387582, @ihurbain raises that maybe we can have a broader discussion about what belongs in the TOC from transcluded content, rather than just mimicking the limitations of the legacy parser

Usually we do "strip kill markers" in the legacy parser, which just removes non-wikitext content entirely.
