Issue created from fantomas-online

Formatted code

type internal Foo private () =
    static member Bar : int option =
        if thing = 1 then
            printfn "hi"
        else if veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLong
                |> Seq.forall (fun (u: VeryVeryVeryVeryVeryVeryVeryLong) -> u.Length = 0) then  //
            printfn "hi"
        else
            failwith ""

Reformatted code

type internal Foo private () =
    static member Bar : int option =
        if thing = 1 then
            printfn "hi"
        else if veryVeryVeryVeryVeryVeryVeryVeryVeryVeryVeryLong
                |> Seq.forall (fun (u: VeryVeryVeryVeryVeryVeryVeryLong) -> u.Length = 0) then //
            printfn "hi"
        else
            failwith ""

Problem description

Fantomas was not able to produce the same code after reformatting the result.

It added an extra space before the comment, which it then tries to take away again.

Extra information

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