Fix regression in panel select animation.

Browse Source 
Currently we are required to update computeYPositions twice per selection. Without doing this, panels are in the wrong place when using keyboard selection.

There's still a bit of work to be done to make this work correctly. It's caused by a race condition of state application for panels which have not yet been presented (and get their state applied in LoadComplete which breaks the order of things).
