Q:

SVG  won't scale like the others

I'm having trouble with a particular icon not scaling.  If you go to this plunker you'll see the very first icon (the cup with the pencil, paint brush and ruler) doesn't respond to the space like every other svg element on the page.
I designed them all in Illustrator cc18 using save to generate the svg code.
For that particular icon Illustrator gives me this code.

the way I'm using it in the HTML is the same for every icon which is like this
<div style="display:grid; grid-template-columns: 1fr 1fr 1fr 1fr; grid-auto-rows: 20vh;">

    <div style="grid-area:1/1/2/2;">
        <svg class="graphicA">
            <use xlink:href="assets/symbol_sprite.svg#illustration_icon" />
        </svg>
    </div>

    <div style="grid-area:1/2/2/3;">
        <svg class="graphicA">
            <use xlink:href="assets/symbol_sprite.svg#......" />
        </svg>
    </div>

    <div style="grid-area:1/3/2/4;">
        <svg class="graphicA">
            <use xlink:href="assets/symbol_sprite.svg#......" />
        </svg>
    </div>

    <!-- etc. etc. -->

</div>

You can refer to the plunker for the full code.  Does anybody readily see what might be stopping this icon from scaling like the others?

A:

There is a typo in the code, regarding viewBox.
<symbol viewbox="0 0 79 146" id="illustration_icon">

should be:
<symbol viewBox="0 0 79 146" id="illustration_icon">
