This is quite a well known issue and there for a good reason I suspect, so I'd urge you to reconsider the fix as by removing it you have probably introduced jerky animations to mobile: http://stackoverflow.com/questions/2946748/iphone-webkit-css-animations-cause-flicker What would be better is to not apply animations willy nilly. In mobile we have a class called animations that only gets applied to the html when animations can be run safely. It would be good to only apply vector-animateLayout for browsers we know that can cope with it.

There's been a duplicate bug report and at least one person complaining about this on IRC (today), in addition to what Brion pointed out in comment 0. We rarely get that much feedback about broken features, and if non-developers report a bug this many times, then it means it's pretty noticeable, so I opted to revert this and consider solving the issue better later. If you can solve the issue better, by all means do :)
