Rotation applied multiply times when I'm zooming map

Hi.
Rotation applied multiply times when I'm zooming map

When I inspect marker on the "Elements" tab in Chrome DevTools, I saw that rotateZ(45deg); added multiply times.

<img src="icon.png" class="leaflet-marker-icon leaflet-zoom-hide leaflet-clickable" tabindex="0" style="margin-left: -17.5px; margin-top: -17.5px; width: 35px; height: 35px; left: 731px; top: 475px; z-index: 475; transform-origin: center center; transform: rotateZ(45deg) rotateZ(45deg);">

change this line (and you might get rid of the IE6 conditional too):

- this._icon.style[L.DomUtil.TRANSFORM] += ' rotateZ(' + this.options.rotationAngle + 'deg)';
+ this._icon.style[L.DomUtil.TRANSFORM] = ' rotateZ(' + this.options.rotationAngle + 'deg)';
