Most examples are uncategorized in Examples panel

[1ec5]

The panel that appears when pressing the Examples button shows most of the examples as being uncategorized, despite them being categorized on the wiki page that it gets the examples from. Specifically, every category’s first example shows up under the category, but each of the category’s subsequent examples show up in the unlabeled category.

This issue appears to have been caused by MediaWiki (justifiably) wrapping each section in a <section> tag in Parsoid 1.6.0.

This became a nonissue upstream when Parsoid was replaced by the PHP parser in wikimedia/wikidata-query-gui@45149ba. The specific fix was to make wikibase.queryService.api.QuerySamples._findPrev() recursive.
