					"body": "Actually, it turns out that this is a very serious problem on several levels:\r\n\r\n* {{autoreverse}} (the key to many of these issues) does not properly reverse ALL changes - for example, if I animate background color changes, the background color does not revert to the original value.\r\n* The current animation subsystem is using antiquated methods (begin/commit) instead of more modern block dispatch. This appears to be causing some performance and synchronization problems, part of what leads to 'fuzzing' and bad/mixed-up behavior that this bug is related to.\r\n* Animation interacts *incorrectly with the view drawing subsystem*. This is the most important: calling {{\\-\\[TiViewProxy reposition]}} triggers not just a refresh, but also a queuing of the view (and all of its subviews, AND possibly its parent) into the view layout processing system - meaning that there is both the immediate resize behavior *and* a queued resize which occurs after the animation has been completed (this leads to a lot of the \"laying out while animating\" messages seen in development). Note that this may not be as severe as I initially assumed (unrelated to this bug), but does cause unnecessary layout passes, possible bad interactions, and other nasties.",
