title: Why is body.scrollTop deprecated?
body: <p>It seems <code>body.scrollTop</code> (and <code>body.scrollLeft</code>) are deprecated in ES5 strict-mode. What is the reason for this, given that it still seems okay to use these properties on other <code>DOMElement</code>s?</p>
  
  <p>Background Info:</p>
  
  <p>I have a function that tries to increase (or decrease, as specified) the <code>scrollTop</code> values of all the ancestors of an <code>element</code>, till one of these actually changes. I am wondering if, to stay complaint with strict-mode, I should specifically check against the <code>body</code> element as the chain of parents moves upward.</p>
  
  <p>[Obviously, <code>body</code>refers to <code>document.body</code>]</p>
