Tile component also if height is set initially to NaN,
doesn't seem to update its height after its creation. If i reduce
its width, a vertical scrollbar appears and if I make it wider,
empty space will remain at the bottom. If I tried to extend it, how
could I retrieve its actual height so that I can resize it?
Container.contentPane.loaderInfo.content seems to contain the
needed data, but how could I access to it considering that
contentPane is internal?
