I have spotted easily reproducible odd behavior with PreservePositionWhenMaximized="True" & telerik:TileViewPanel.IsVirtualized="True" where a maximized tile is swapped to a minimized state.
To simplify demonstrating the problem, I suggest setting MaximizeMode="One" & MinimizedItemsPosition="Right". (Note: Happens for any MaximizeMode &/or MinimizedItemsPosition setting.)
The steps to reproduce are:
1. Select the "First" Tile so it is maximized
2. Select the "Second" Tile - first swaps with second
3. Now Select any tile from the "3rd Tile onwards" and the "Second" Tile covers the "First" Tile - does not return to the "Second" Tile position beneath the "First" Tile.
I am using v2013.2.724.1050 & believe that this is a bug. Can someone please confirm and advise if there is a work-around.
