Snap SVG 在悬停时重复在重复悬停时变慢

Question

有一个简单的 snap.svg 悬停时旋转动画。 Cog 在悬停时旋转并在悬停时停止。

在第一次悬停时工作正常 in/out 但在重复悬停时动画每次都会减慢（减半？）。不知道为什么会这样。

这是我目前拥有的：

<script> 
var cogs = Snap("#cogs");
var cog1 = cogs.select(".cog1");

cogs.hover(function cogs(){
cog1.stop().animate({ 'transform' : 'r-180,110,110' }, 5000, 
function(){ 
  cog1.attr({ transform: 'rotate(0 110 110)'});
})
cogs();
}, function() {
  cog1.stop(); 
});
</script>

Just 和 TweenMax JS 库用于高级控制、平滑运动和性能！ https://jsfiddle.net/hpz19wrc/2/

// 
var tl = new TimelineMax(),
 cogs = Snap("#cogs"),
 cog1 = cogs.select(".cog1");

// aniamtion
tl.to(".cog1", 5, {
 rotation: 360 , 
 repeat: -1, 
 transformOrigin: 'center',
 ease: Power0.easeNone
});

// control
tl.pause();
cogs.hover(function(){
  tl.resume();
}, function() {
  tl.pause();
});
