Drop FloatingDocumentWindow into DocumentPane is not consistent (when FloatingDocumentWindow contains LayoutAnchorable)

[Dirkster99]

Precondition

• AvalonDock.Layout.config file is not present in MLibTest bin folder
• LayoutAnchorables can be docked into a LayoutDocument:
  Make sure the line anchorableToShow.CanDockAsTabbedDocument = false; is commented out or not present in LayoutInitializer.BeforeInsertAnchorable(...)

Test Case 1

• Start MLibTest

• Open 3 text files via Files>Open
  

• Drag & Drop 2 documents out of the MainWindow into a FloatingDocumentWindow
  

• Drag & Drop a LayoutAnchorable (toolwindow) into the FloatingDocumentWindow
  

• Drag & Drop FloatingDocumentWindow into one of the outer drop buttons of the DocumentPane (e.g. Left most drop button)
  

• Result: OK (both documents and the Anchorable are present in the expected position)
  

Test Case 2

(same pre-conditions as Test Case 1)

• Start MLibTest

• Open 2 text files via Files>Open
  

• Drag & Drop 2 documents out of the MainWindow into a FloatingDocumentWindow
  

• Drag & Drop a LayoutAnchorable (toolwindow) into the FloatingDocumentWindow
  

• Drag & Drop FloatingDocumentWindow into the center drop button of the DocumentPane
  

• Result: NOT OK (the Anchorable - Tool 3 in screenshots - is no longer present in the application and cannot be viewed anymore)
