Looping Animations (Changes to SL3)

Hello all!

Loving the changes to SL3 (especially the smoother HTML effects), however I'm finding that my looping animations are now acting differently. A constant spin (using a half turn entrance and half turn exit paired with triggers to repeat) now increases the rate of spin. Instead of a continuous spinning animation, the loop now seems to double in speed each time.  I have found this with Spin and Spin and Shrink.

Anyone experiencing the same? It's actually quite mesmerizing and comical to view, but I wonder if this new behavior is intentional, as it prevents constant spinning (though it should still work using the layer trick).
