Frequent crash in WindowChromeBehavior -> GetHitTestResult

[Aaron-Stewart-RPS]

Describe the bug

I am getting a fairly frequent reports from the field as follows:

System.InvalidOperationException: This Visual is not connected to a PresentationSource.
- at System.Windows.Media.Visual.PointFromScreen(Point point)
- at ControlzEx.Behaviors.WindowChromeBehavior.GetHitTestResult(IntPtr lParam) in C:\projects\controlzex\src\ControlzEx\Behaviors\WindowChrome\WindowChromeBehavior.MessageHandling.cs:line 470
- at ControlzEx.Behaviors.WindowChromeBehavior.WindowProc(IntPtr hwnd, Int32 msg, UIntPtr wParam, IntPtr lParam, Boolean& handled) in C:\projects\controlzex\src\ControlzEx\Behaviors\WindowChrome\WindowChromeBehavior.MessageHandling.cs:line 139
- at ControlzEx.Behaviors.WindowChromeBehavior.WindowProc(IntPtr hwnd, Int32 msg, IntPtr wparam, IntPtr lparam, Boolean& handled) in C:\projects\controlzex\src\ControlzEx\Behaviors\WindowChrome\WindowChromeBehavior.MessageHandling.cs:line 112
- at System.Windows.Interop.HwndSource.PublicHooksFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)
- at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)
- at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o)
- at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
- at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

That is the simplest call stack I have but I have a few others that all point back to GetHitTestResult in WindowChromeBehavior.

Steps to reproduce

Unfortunately I cannot reproduce it locally, all I have are application crash reports.

That issue should already be fixed in the upcoming 7.0 version.
