Support reports with no source labels

[Nyrox]

Right now, if I try to create a report with no source labels e.g like this

ariadne::Report::build(ReportKind::Error, 0..0)
                .with_code(3)
                .with_message("Some error occured")
                .with_note("X is causing this error")
                .with_help("Do this to fix it")
                .finish()

then ariadne renders only the message, completely omitting the note and help text.

I have to add an empty label to get them to show up, but this is quite ugly (obviously).

As ardiane is primarily a compiler diagnostics crate I understand you would usually have a source, but in this case I am trying to render an error for the absence of a file / property and there is no good source to relate the error to, but I still want the error to be consistently formatted with the rest of the errors.

Is there any way to print an ariadne formatted Report without a source?

At the very least it should be documented somewhere. I fully expected notes and help to be independent from labels, because their add and with methods are on Report, not on Label. It is quite confusing to see notes and help (apparently randomly) disappear.
