A pipeline contains 4 stages, 2 middle ones are disabled (see screenshot). When I copy the pipeline to clipboard, those middle stages are still denoted with commas, like so:

{ $match: {  "imdb.rating": {$gte:7},  genres: { $nin: ["Crime", "Horror"] },  rated: { $in: ["PG", "G"]},  languages: { $in: ["English","Japanese"] }} }, , , { $count: "movies" }
