Trying to understand relationship between margin and format_docstrings

[danielsoutar]

Straightforward question: does setting margin to 80 characters apply to docstrings as well if format_docstrings is set to true?

Environment:
VSCode, using the Julia extension (v1.38.2)

Format config options:
style = "blue"
margin = 80
trailing_comma = true
import_to_using = false
remove_extra_newlines = false
format_docstrings = true

Before:

"""
    some_really_long_function_name!(really_long_arg_a, argument_named_b)::Nothing

Do nothing and make a really big deal out of it. For more details see https://www.example.com/.

# Arguments

- `really_long_arg_a`: First argument
- `argument_named_b`: Second argument

"""
function some_really_long_function_name!(really_long_arg_a, argument_named_b)::Nothing
    nothing    
end

After:

"""
    some_really_long_function_name!(really_long_arg_a, argument_named_b)::Nothing  # still over 80 characters

Do nothing and make a really big deal out of it. For more details see https://www.example.com/  # still over 80 characters

# Arguments

  - `really_long_arg_a`: First argument
  - `argument_named_b`: Second argument
"""
function some_really_long_function_name!(
    really_long_arg_a, argument_named_b
)::Nothing
    return nothing
end

Both the signature and first line exceed the margin, and yet neither are formatted. Is this intentional? I understand if CommonMark takes care of formatting markdown, but this section in the README would lead me to think that this is unexpected:

format_docstrings
default: false
Format code docstrings with the same options used for the code source.
Markdown is formatted with CommonMark alongside Julia code.

I'm guessing the signature is not being interpreted as a code block
