Empty width attribute causes undesired SVG width

Screenshot:

I'm thinking it might be better to not apply empty attributes to the SVG. Would it be possible to only return attributes if they have values?

 public function getSvgConfig()
  {
    // Get the config from the params
    $class = $this->getParam('class');
    $height = $this->getParam('height');
    $width = $this->getParam('width');

    // Add the config to an array and return it.
    return [
      'class' => ((false) ? null : $class),
      'height' => ((false) ? null : $height),
      'width' => ((false) ? null : $width)
    ];
  }

@benfurfie Looks like this is also causing console errors.

Good suggestion. I'll look at adding it, unless you want to do a PR?
