Add watermark to animated gif with PHP ImageMagick library

Question

This works fine for none animated images:

$image = new Imagick($file);

$format = strtolower($image->getImageFormat());

$watermark = new Imagick('watermark.png');
$watermark->scaleImage($image->getImageWidth(), $watermark->getImageHeight());

$image->addImage($watermark);

$image->resetIterator();
$combined = $image->appendImages(true);

$data = base64_encode($combined->getImageBlob());

echo '<img src="data:image/' . $format . ';base64,' . $data . '">';

How can I make this work for animated gifs? It just puts every frame below each other and the watermark below that.
