Inline SVG breaks in Safari and Mobile Safari

问题:

I recently launched a site which used a bit of inline SVG.

<svg class="divider-icon" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     viewBox="0 0 55.221 58.079" enable-background="new 0 0 55.221 58.079" xml:space="preserve" preserveAspectRatio="xMidYMid meet">
     <path d="[...]"/>
</svg>

Everything was perfect in Chrome and Firefox, but when I tested on an iPhone or in desktop Safari, the layout was completely broken and many of the SVGs were missing. I ran the source through the W3C validator and everything was find. I work with SVG a lot, so this was very confusing...

It turns out that Safari and Mobile Safari freak out if you omit the height and width attributes I was setting the dimensions with CSS, which worked fine in other browsers. But I had to add those attributes back in to make it behave consistently:

<svg class="divider-icon" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     width="55.221px" height="58.079px" viewBox="0 0 55.221 58.079" enable-background="new 0 0 55.221 58.079" xml:space="preserve" preserveAspectRatio="xMidYMid meet">
     <path d="[...]"/>
</svg>

Notice the width and height attributes that were missing above.

Also, it's interesting to point out that the value of preserveAspectRatio matters. I had a couple other inline SVG elements that had preserveAspectRatio="none meet" and they were unaffected by this issue.
