The annotation reference tests now show the date/time placeholder, but since localization is not active we don't see the actual date/time string. It would be nice to be able to have this in the reference images.
const svg = document.createElementNS(SVG_NS, "svg:svg");
    svg.setAttribute("width", `${viewport.width}px`);
    svg.setAttribute("height", `${viewport.height}px`);
    const foreignObject = document.createElementNS(SVG_NS, "svg:foreignObject");
    foreignObject.setAttribute("x", "0");
    foreignObject.setAttribute("y", "0");
    foreignObject.setAttribute("width", `${viewport.width}px`);
    foreignObject.setAttribute("height", `${viewport.height}px`);
    const style = document.createElement("style");
    foreignObject.append(style);
    const div = document.createElement("div");
    foreignObject.append(div);
    return { svg, foreignObject, style, div };
  }
