宽度和高度在 SVG <use> 元素中不起作用

Question

我尝试使用不同大小重复相同的 use 元素，但它不起作用：

<svg id="svg">
        <defs>
            <g id="phone"><path d="M19.494,0H7.948C6.843,0,5.951,0.896,5.951,1.999v23.446c0,1.102,0.892,1.997,1.997,1.997h11.546
                    c1.103,0,1.997-0.895,1.997-1.997V1.999C21.491,0.896,20.597,0,19.494,0z M10.872,1.214h5.7c0.144,0,0.261,0.215,0.261,0.481
                    s-0.117,0.482-0.261,0.482h-5.7c-0.145,0-0.26-0.216-0.26-0.482C10.612,1.429,10.727,1.214,10.872,1.214z M13.722,25.469
                    c-0.703,0-1.275-0.572-1.275-1.276s0.572-1.274,1.275-1.274c0.701,0,1.273,0.57,1.273,1.274S14.423,25.469,13.722,25.469z
                     M19.995,21.1H7.448V3.373h12.547V21.1z"/></g>
        </defs>
        <use href="#phone" class="tool-icon" width="50px" height="50px"/>
        <use href="#phone" class="tool-icon" width="200px" height="200px" x="60px"/>
    </svg>

我究竟做错了什么？

宽度和高度对使用元素没有影响，除非引用的元素有一个视图框
