Record member declarations can break with Stroustrup enabled

[josh-degraw]

Issue created from fantomas-online

Code

namespace Some.Namespace

[<Interface>]
type IEvent = interface end

type SomeEvent =
    { Id: string
      Name: string }
    interface IEvent

type UpdatedName = { PreviousName: string }

Result

namespace Some.Namespace

[<Interface>]
type IEvent =
    interface
    end

type SomeEvent = {
    Id: string
    Name: string
} with

    interface IEvent

    type UpdatedName = { PreviousName: string }

Problem description

We use an empty interface for a few things, and updating my code to run the latest alpha seems to break in those places when I turn on the Stroustrup setting if anything comes afterwards. I'll try and get a PR up for this soon.

Extra information

• The formatted result breaks my code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

Options

Fantomas v6 branch at 3/6/23

    { config with
                MultilineBracketStyle = Stroustrup }

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

Just an FYI, this breaks with other stuff as well: example

We are probably missing some unindent call under the right conditions.
