On this page javascript is changing 'display' attribute between 'block' and
'none'. Change block->none works good, but after changing none->block page
scrolls down.
Function changeDisplay() - it's activated after clicking on horizontal bar with
3 dots.

Reproducible: Always

Steps to Reproduce:
1. Scroll page to the begining.
2. Click the bar to hide the div block.
3. Clock the bar to show it again.

Actual Results:  
Page is scrolled to bottom.

Expected Results:  
Leave scroll position in the same place as it was before the change.

This happens because it is a link that points to an anchor in the same page.
You can prevent this from happening by using this:
<a href="#newsy" onclick="changeDisplay(event)"><img
src="news_files/belka-srodek.gif" alt="" height="16" width="750"></a>

 and this as function:
    function changeDisplay(e) { var newsy = document.getElementById('newsy');
newsy.style.display = (newsy.style.display == 'block')? 'none': 'block';
e.preventDefault(); }
