Issue created from fantomas-online

Code

type SomeType() =

    let mutable v: string = ""

    member val SomeAutoProp: float = 23.42 with get, set
    
    member this.MyProperty
        with get (): string = v
        and set (value: string): unit = v <- value

Result

type SomeType() =

    let mutable v : string = ""

    member val SomeAutoProp : float = 23.42 with get, set

    member this.MyProperty
        with get (): string = v
        and set (value : string): unit = v <- value

Problem description

Expected code:

type SomeType() =

    let mutable v : string = ""

    member val SomeAutoProp : float = 23.42 with get, set

    member this.MyProperty
        with get () : string = v
        and set (value : string) : unit = v <- value

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.
