MergedDictionary Items does not merge

[ghost1372]

there is some file like this:

Text.xaml:

<ResourceDictionary
    xmlns:converters="clr-namespace:iNKORE.UI.WPF.Modern.Common.Converters">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary>
              <converters:test key="test"/>
        </ResourceDictionary>
    </ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

in this case, converters does not merge into our single xaml file and will be skipped. so xamltools should support merged dictionary in resource dictionary
