For removed items that are not be replaced by another item, the leave-animation doesn't run correctly. The removed items are instantly disappearing except for the left border of the item, the left border is then disappearing after the duration as expected.

Items that are removed, but replaced with another item are animated correctly.
I use overflow:auto on the div which contains the FlipMove node. Removing the overflow gives the animations another look, though it is buggy too. Nevertheless, overflow is really a necessity anyway.
It is solved by making sure the parent of the grid is set to width:100%, the animations are hidden because the width is lowered instantly before the animation has time to be shown.
