Edited Issue: AvalonDock: LayoutAnchorable remains hidden after executing LayoutAnchorable.show() [22470]

__Preconditions:__

* Create simple layout with horizontally orientated LayoutAnchorablePane containing three LayoutAnchorable's (e.g., see project attached: AvalonDockBug.zip);
* Add two buttons: SHOW (codebehind: LayoutAnchorable#1.Show()) and HIDE (codebehind: LayoutAnchorable#1.Hide());

__Error path:__

* Hide leftmost anchorable (LayoutAnchorable#1) by pressing HIDE-button;
* Dock (by drag and drop) the rightmost anchorable (LayoutAnchorable#3) to the bottom;

__Error:__
* LayoutAnchorable#1 remains hidden after pressing SHOW-button;

__Remark:__
* The error cannot be reproduced by docking the rightmost anchorable on top (or left/right sides) of the window;
