Created Unassigned: Enable to show/hide LayoutAnchorable [21970]

Hi,

I have a menu that contain all LayoutAnchorable that my application can display. The IsCheck depency property of MenuItem is binded to corresponding LayoutAnchorable Visible dependency property. So when I click on a menu item to show or hide the corresponding LayoutAnchorable.

It's in all version since 2.3.

My problem is the follow:
I have some LayoutAnchorable hiden and a layout where the RootPanel is vertical. After I drag and drop a LayoutAnchorable on right I can't show the hiden LayoutAnchorable.

I have fix this problem has proper I can:
In LayoutDocumentFloatingWindowControl::OnClosed() and LayoutAnchorableFloatingWindowControl::OnClosed() check if CloseInitiatedByUser before call "root.CollectGarbage();".

Contact me for any question or détail analysis.
