Agg Pipeline Builder does not allow comments, confusing error message

This may not be supported but I'm raising it anyway, perhaps as a feature request.

Affected Version

1.14.0-beta.1

Actual Behavior

When adding comments in the editor for aggregation stages, it doesn't parse the objects anymore and instead displays an error expecting a [ or AggStage.

That's confusing and it took me a while that the comment caused this issue.

See attached screenshots.

Expected behavior

The comments are silently ignored.
