Many projects have been using parsoid now.
While doing some code cleanup in MobileFrontend I noticed Kartographer makes use of the mobileFrontend.section-toggled hook which is not present in the Parsoid version and in the legacy parser marked as `Internal for use inside ExternalGuidance.`

Is this still needed? If so could you provide context on what bug it is addressing so the #readers-growth team can consider whether to ?
# TODO
[] Determine if Kartographer still needs it (And if there is a bug in production that has resurfaced relating to this)
[] If needed, update the documentation that Kartographer uses the hook and add it to the Parsoid sectionCollapsing code.
[] If not remove hook from code.
