Transform Origin无法在Firefox中运行

Question

我正在使用CSS Transitions和jQuery激活动画一个SVG组。动画还使用transform-origin: 50% 0%;保持div的中心。它在Chrome和Safari中完美运行，但在Firefox中，转换属性加载正常，但transform-origin无法正常工作。页面是实时的here，我在下面嵌入了相关代码。由于已知的Webkit错误，与SVG过滤器相关的代码已被注释掉。

CSS：

.chartsection {
    -webkit-transition: all .7s ease;
    -moz-transition:    all .7s ease;
    -o-transition:      all .7s ease;
    -ms-transition:     all .7s ease;
    transition:         all .7s ease;
    -webkit-transform-origin:   50% 0%;
    -moz-transform-origin:      50% 0%;
    -o-transform-origin:        50% 0%;
    -ms-transform-origin:       50% 0%;
    transform-origin:           50% 0%;
}

jQuery的：

function goToStud() {
$('#studchart').css({
    '-webkit-transform': 'scale(' + studScaleUp +')',
    '-moz-transform': 'scale(' + studScaleUp +')',
    '-o-transform': 'scale(' + studScaleUp +')',
    '-ms-transform': 'scale(' + studScaleUp +')',
    'transform': 'scale(' + studScaleUp +')'
})/*.attr("filter", "url(#noblur)")*/;

$('#guestchart').css({
    '-webkit-transform': 'scale(' + guestScaleDown +') translateY(' + guestMoveDown + 'px)',
    '-moz-transform': 'scale(' + guestScaleDown +') translateY(' + guestMoveDown + 'px)',
    '-o-transform': 'scale(' + guestScaleDown +') translateY(' + guestMoveDown + 'px)',
    '-ms-transform': 'scale(' + guestScaleDown +') translateY(' + guestMoveDown + 'px)',
    'transform': 'scale(' + guestScaleDown +') translateY(' + guestMoveDown + 'px)'
})/*.attr("filter", "url(#fullblur)")*/;

hideTitles(500);
}
