Fantomas corrupts an explicit constructor with `then` clause

[xperiandri]

Issue created from fantomas-online

Code

type CreateBuildingViewModel =
    inherit ResizeArray

    new (items) as vm
        =
        let p = ""
        {
            inherit ResizeArray(seq {
                yield p
                yield! items
            })
        }
        then
            vm.program <- p

    [<DefaultValue>]
    val mutable program : string

Result

type CreateBuildingViewModel =
    inherit ResizeArray

    new(items) as vm =
        let p = ""

        { inherit
            ResizeArray(
                seq {
                    yield p
                    yield! items
                }
            ) }

        vm.program <- p

    [<DefaultValue>]
    val mutable program: string

Hi, thank for the report.
Your .editorconfig is irrelevant to this problem, so please don't bring it up as it only adds to the cognitive load.
