<svg> className is removed

[groenroos]

If the <svg> tag in the image being loaded has a class, this will be overridden when the SVG is inlined:

SVG file

<svg class="someclass" xmlns="http://www.w3.org/2000/svg" width="53" height="27" viewBox="0 0 53 27">
    <circle cx="26.5" cy="13.5" r="8" fill="#FFF" fill-rule="evenodd" />
</svg>

Expected outcome

<svg class="someclass svg inlined-svg" xmlns="http://www.w3.org/2000/svg" width="53" height="27" viewBox="0 0 53 27">
    <circle cx="26.5" cy="13.5" r="8" fill="#FFF" fill-rule="evenodd" />
</svg>

Actual outcome

<svg class="svg inlined-svg" xmlns="http://www.w3.org/2000/svg" width="53" height="27" viewBox="0 0 53 27">
    <circle cx="26.5" cy="13.5" r="8" fill="#FFF" fill-rule="evenodd" />
</svg>

I know as a workaround I can define the class in the <img> tag and it'll be retained, but this seems redundant/inconvenient.
