This should fix the problem with flickering and positioning tooltips for spells on cooldown. There's still room for a race condition, so every so often, yes the tooltip will fall to the bottom right corner. I'll adjust this threshold as needed if I find it works better. I've done little testing on this to find the sweet spot.
