RightWindowCommands no more visible when ShowTitleBar is False

Starting from MahApps 1.6.2, setting ShowTitleBar to False along with RightWindowCommands does not work anymore. The RightWindowCommands is not shown whereas it should be.

Expected outcome

The RightWindowCommands should always be visible, like it was before and behave the same than WindowButtonCommands.

Environment

• MahApps.Metro v1.6.2
• Windows OS 16299
• Visual Studio 2017
• .NET Framework 4.7.1

@bbougot It's more a combination with a feature and a bug (which I fixed now). Normally if you set the ShowTitleBar to false then all window commands except the button window commands should be collapsed. If you don't want this, then you can set then LeftWindowCommandsOverlayBehavior and RightWindowCommandsOverlayBehavior to HiddenTitleBar or Always to force it to shown.

In version 1.6.4, if I set ShowTitleBar to false, and RightWindowCommandsOverlayBehavior to Always, then a white background title bar would appear. Previously, in older version, the commands overlay blend into the window.

I confirm what programatix say, the behavior didn't work as expected, when the behavior is set the title bar is simply show even if the ShowTitleBar is set to false
