Opening namespace in module with multiline attributes puts the open into a wrong position (within attributes)

[xperiandri]

Repro steps

1. Create a new project
2. Paste

namespace X

open System

[<RequireQualifiedAccess;
  CompiledName((nameof System.Collections.Immutable.ImmutableArray)
               + "Module")>]
module FlatList =

    let a : KeyValuePair<string, int> = KeyValuePair<string, int>("key", 1)

3. Put the cursor at KeyValuePair
4. Press Ctrl+. to trigger light bulb
5. Select opening the namespace in light bulb menu
6. See

namespace X

open System

[<RequireQualifiedAccess;
  CompiledName((nameof System.Collections.Immutable.ImmutableArray)
    open System.Collections.Generic

               + "Module")>]
module FlatList =

    let a : KeyValuePair<string, int> = KeyValuePair<string, int>("key", 1)

Expected behavior

namespace X

open System
open System.Collections.Generic

[<RequireQualifiedAccess;
  CompiledName((nameof System.Collections.Immutable.ImmutableArray)

               + "Module")>]
module FlatList =

    let a : KeyValuePair<string, int> = KeyValuePair<string, int>("key", 1)

Actual behavior

namespace X

open System

[<RequireQualifiedAccess;
  CompiledName((nameof System.Collections.Immutable.ImmutableArray)
    open System.Collections.Generic

               + "Module")>]
module FlatList =

    let a : KeyValuePair<string, int> = KeyValuePair<string, int>("key", 1)
