Draw bug in OpenLayers.Handler.Box with firefox

[openlayers]

Hi. I've found a problem in OpenLayers.Handler.Box; when you draw a box and move fast from negative to positive coordinates in firefox, the mouse cursor do not follow exactly the box. The code that give problem is :

if (xy.x < this.dragHandler.start.x) {

this.zoomBox.style.left = xy.x+"px";

} if (xy.y < this.dragHandler.start.y) {

this.zoomBox.style.top = xy.y+"px";

}

if you move the mouse very fast, firefox lose some events and the top/left value remain with old values also if i go in positive area.

Patch file attached.

(In [7375]) "Draw bug in OpenLayers.Handler.Box with firefox". Now always set style.left and style.top, so lost events won't result in an incorrect box any more. r=me (closes #1579)
