SVG with GIF inside. How to freeze the animation?

We discovered that you can place animated GIFs inside of the SVG. This makes freezing animation very interesting problem. Example is on the site Neutec

Animations have to be frozen before screenshots are taken, otherwise visual regression testing flags them as changes on every run.

Here is a way to freeze it with javascript:

const image = document.querySelector('#Layer_1 image[*|href$=".gif"]');

if (image) {
    const c = document.createElement('canvas');
    const w = c.width = image.getAttribute('width');
    const h = c.height = image.getAttribute('height');

    c.getContext('2d').drawImage(image, 0, 0, w, h);
    image.setAttributeNS('http://www.w3.org/1999/xlink', 'href', c.toDataURL('image/gif'));
}
