CSS Overflow: overlay. Is it deprecated? How can I replace it?
<p>I have a legacy web app with non-standard css property value;</p>

<pre><code>myClass{
    overflow: overlay;
}
</code></pre>

<p>I googled a bit, but did not found much about this property.<br>
<a href="http://quirksmode.org/css/css2/overflow.html" rel="noreferrer">This link</a> says that it works like <code>overflow:auto</code> for webkit browsers, but it is false.<br>
<a href="https://jsfiddle.net/11w3LLq1/" rel="noreferrer">Simple sample to show the difference and existance of this value.</a> Checked in last chrome.</p>

<p>Is it deprecated now?<br>
Is it a crutch for legacy browsers? (What browsers exactly?)<br>
What is the semantic of this value?<br>
Should I replace it?<br>
How can I replace it?   </p>
