Issue Details

我在使用了 toolbox 中的 dataZoom 区域缩放功能后，想要鼠标悬浮在图形元素上的 cursor 样式为默认的 pointer ，而不是 crosshair 。也尝试使用 chart.getZr().setCursorStyle('pointer') 来修改鼠标悬浮样式，但开启工具箱 dataZoom 功能后，源码中是让整个图表为 crosshair 效果，并不能达到我想要的效果，请问这个问题可以优化吗，或者我该如何解决呢？

Expected Behavior

Current Behavior

Online Example

源码中重置 cursor 函数：

function resetCursor(controller, e, localCursorPoint) {
    // Check active
    if (!controller._brushType) {
        return;
    }

    var zr = controller._zr;
    var covers = controller._covers;
    var currPanel = getPanelByPoint(controller, e, localCursorPoint);

    // Check whether in covers.
    if (!controller._dragging) {
        for (var i = 0; i < covers.length; i++) {
            var brushOption = covers[i].__brushOption;
            if (currPanel
                && (currPanel === true || brushOption.panelId === currPanel.panelId)
                && coverRenderers[brushOption.brushType].contain(
                    covers[i], localCursorPoint[0], localCursorPoint[1]
                )
            ) {
                // Use cursor style set on cover.
                return;
            }
        }
    }

    currPanel && zr.setCursorStyle('crosshair');
}
