Long parameter attribute gives weird line break before type annotation

[cmeeren]

Issue created from fantomas-online

Code and expected output

type Query() =

    member _.SearchOrders
        (
            [<GraphQLType(typeof<ListType<NonNullType<InputObjectType<SearchOrdersSortItem>>>>)>]
            sort: SearchOrdersSortItem list option
        ) =
        ()

Result

type Query() =

    member _.SearchOrders
        ([<GraphQLType(typeof<ListType<NonNullType<InputObjectType<SearchOrdersSortItem>>>>)>] sort:
            SearchOrdersSortItem list option)
        =
        ()

Problem description

When a parameter has a long attribute (several shorter attributes would presumably also give the same effect), the line is broken before the type annotation.

While this particular case is not covered explicitly by the F# code formatting guidelines, the guidelines specify attributes on a separate line in all other (non-parameter) cases, so I believe it would be most consistent to place the attribute on a separate line also in the case of very long attributes.

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.
• I would like a release if this problem is solved.
