Steps to reproduce:
Observe:
No buttons are displayed.
Notes:
The section heading HTML looks like it (almost?) matches, excusing the additional noise that Parsoid plops into its HTML like IDs. A thing I know to be different between Parsoid and legacy is that Parsoid includes <section> and legacy does not, though I can see that only being relevant if XFDCloser is picking the headings by doing something like .mw-parser-output > .mw-heading which would be kind of weird.
