Offside error splitting long line

[Smaug123]

Issue created from fantomas-online

Code

module Foo =
    let bar () =
        let saveDir =
            fs.DirectoryInfo.FromDirectoryName(fs.Path.Combine((ThingThing.rootRoot fs thingThing).FullName, "tada!")).EnumerateDirectories()
            |> Seq.exactlyOne
        ()

Result

module Foo =
    let bar () =
        let saveDir =
            fs
                .DirectoryInfo
                .FromDirectoryName(fs.Path.Combine (
                    (ThingThing.rootRoot fs thingThing).FullName,
                    "tada!"
                ))
                .EnumerateDirectories ()
            |> Seq.exactlyOne

        ()

Problem description

When the line length is short enough that the Path.Combine needs to split here, we end up with an offside error.

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