JavaScript: GIF file loses animation

Question

I am trying to set a hidden layer (containing animated GIFs) visible. Initially, the layer is hidden using

display: none;

However, when I try to show the layer using javascript:

document.getElementById('loading_layer').style.display = 'block';

the layer is displayed, but the images inside it are no longer animated. What could be the reason for this?

Thats an Internet Explorer bug. One workaround is:

document.getElementById('loading_layer').innerHTML = document.getElementById('loading_layer').innerHTML;
