Web page doesn't show animated object with entry page link.

Reproducible: Always

Steps to Reproduce:
1. Load http://www.dr-krapp.de in Mozilla
2. Load page in Netscape
3. compare

Actual Results:  
The page displayed, but the main link to the real entry page is missing,
together with some image.
I guess this is because the object has initial "visibility: hidden" and the
script is expected to change that to visible, yet for some some strange reason
Mozilla fails to do this properly (maybe the script doesn't even get executed ??).

Expected Results:  
Proper execution of this animated object, creation/displaying of the link.

Has been annoying me since Mozilla 1.0 RC releases or earlier.

Screenshots will be attached for evidence.

As I'm totally unexperienced with this kind of "dynamic" content (I'm a Wine
developer), I'd like to know what is broken and why, and, most importantly,
whether it's the web page that should be fixed somehow and if so, *how* it
should be fixed (in order to tell those people to fix it).

Searching for "visibility" seems to suggest that there are several other bug
reports (#complaining about a lack of robustness in this area.

Given that this bug completely blocks access to a whole website by hiding the
entry link to the real page
(and after all this bug could render whole subparts of websites invisible !!)
and a lot of other bug reports seem to mention it, I'm assigning Severity Major
to it.

Needless to say, I did make sure that I had scripting fully enabled ;-)

I selected Component "DOM Other", but this may be not too close or entirely
wrong, so place change it to the proper Component.

Thanks !!

Just in case the page decides to change its face or so...

This script is worked, but it made Mozilla-ignored. OnLoad of this page function
function dynAnimation(obj) is called (in animate.js) Let us check it staring block:

function dynAnimation(obj)
  animateElements = new Array()
  var ms = navigator.appVersion.indexOf("MSIE")
  ie4 = (ms>0) && (parseInt(navigator.appVersion.substring(ms+5, ms+6)) >= 4)
  {if((navigator.appName == "Netscape") &&
       (parseInt(navigator.appVersion.substring(0, 1)) >= 4))				      

So this script support only IE document.all or netscape document.layers, and
does not support Mozilla at all (for mozilla this script return
doc_els=undefined). I think it is Tech Evangelism case.
