Hi,

in new 4.0 AD version new posibility to dock dokument panel in floating window you can create a floating window that cannot be closed.

repro steps:

1. open AD 4.0 MVVMTestApp.exe

2. open random document

3. undock document to floating window

4. drag file stats panel to floating window and dock it as left/top/right/bottom side

Issue 1: the anchorable is missing close/hide button

5. close document in floating window

Issue 2: floating window is missing close button

I can verify both issues. These problems should be fixed but there are some workaround solutions to close the Floating File Stats Tool in the meantime.

You can either:

• drag the File Stats Tool back into the mainwindow and dock it into an outer docking position (normal hide buttons are available now) or
• you can drag on the document tab of the floating File Stats Tool (as indicated by the red arrow in the screenshot below) to make the missing buttons re-appear
  

The discussion in issue 117 is probably related. We might have to undo the quick fix and go for the full implementation for the next release ...

LayoutAnchorable has a property called CanDockAsTabbedDocument which could help to solve this issue. However, it introduces one more side effect - there is no way to intermix documents and anchorables in a floating windows.

Is there any way to have both document and anchorable together in a floating window, but still each of them being a document and anchorable (this means each of them still gets a proper style and do not introduce ugly CanClose side effects) ?
