Some parameters supported by the parsing function of Action API (action=parse), including disabletoc, disableeditsection, wrapoutputclass and disablestylededuplication, won't work if the content being parsed contains a term that is defined in the site's Lingo Glossary extension. (For documentation on the parsing API and these parameters, see https://www.mediawiki.org/wiki/API:Parsing_wikitext)

For example, here is a page without any Glossary term:

If we run this query:

https://example.com/api.php?action=parse&prop=text&page=example_page&section=1&disableeditsection=1

It will correctly return:

However, if the page contained a Glossary term (In this case, "KPI")

And we run the same query:

https://example.com/api.php?action=parse&prop=text&page=example_page&section=1&disableeditsection=1

Then the disableeditsection parameter won't work. Running the same query will return wikitext with edit section texts, which is not supposed to happen.
