Instant Layout Assistant has to be activated twice to insert RibbonControl

Hello,

To insert the RibbonControl using the Instant Layout Assistant it has to be activated 2 times.
Please find a screencast.

Also I'd like to keep XAML code layout when I insert a component.
But the Instant Layout Assistant and Toolbox change the code layout.

As you can see in the screencast, XAML before the insertion:

XAML
<UserControl x:Class="LS12.Module.Shop.Views.ShopRibbonView"  
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"  
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"  
             mc:Ignorable="d" d:DesignHeight="500" d:DesignWidth="800">  

And after the insertion:

XAML
<UserControl  
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"  
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"  
             xmlns:dxr="http://schemas.devexpress.com/winfx/2008/xaml/ribbon" xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core" xmlns:dxb="http://schemas.devexpress.com/winfx/2008/xaml/bars" x:Class="LS12.Module.Shop.Views.ShopRibbonView"  
             mc:Ignorable="d" d:DesignHeight="500" d:DesignWidth="800">  

It isn't critical issue, but I hope it can be fixed in a future releases.

Thanks,
Mikhail
