<p dir="auto">In 1.0.0-beta.20  If I set autoHideDuration={null}, onRequestClose() is triggered immediately as if the value is 0</p>
<ul dir="auto">
<li>[x ] I have searched the <a href="https://github.com/callemall/material-ui/issues">issues</a> of this repository and believe that this is not a duplicate.</li>
</ul>
<h2 dir="auto">Expected Behavior</h2>
<p dir="auto">The docs say autoHideDuration will be disabled if set to null</p>
<h2 dir="auto">Current Behavior</h2>
<p dir="auto">Currently null is treated like 0, however I can set it to undefined and it works like it used to.</p>
<p dir="auto">I want to keep the snackbar visible indefinitely only if there are more details (accessed through a link in the snnackbar), so code looks something like this:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="&lt;Snackbar
      onRequestClose={onDismiss}
      autoHideDuration={hasMoreDetails ? null : 4000}
      action={[ renderDetailsButton(hasMoreDetails),     &lt;CloseButton /&gt;    ]}
/&gt;"><pre class="notranslate"><code class="notranslate">&lt;Snackbar
      onRequestClose={onDismiss}
      autoHideDuration={hasMoreDetails ? null : 4000}
      action={[ renderDetailsButton(hasMoreDetails),     &lt;CloseButton /&gt;    ]}
/&gt;
</code></pre></div>
<p dir="auto">The workaround is fine</p>
<p dir="auto"><code class="notranslate">  autoHideDuration={hasMoreDetails ? undefined : 4000}</code></p>
<p dir="auto">.. but then the docs need updating</p>

Also, on the image above, it has hover color, that's nice too.</p>
