<h2 dir="auto">Problem Description</h2>
<p dir="auto">onFocus not firing on select element, I essentially have this except it has menu elements inside of it:<br>
<code class="notranslate">&lt;SelectField value={value} onFocus={() =&gt; console.log('I am focused')} /&gt;</code><br>
and when I click in the select, no event is being fired.</p>
<h2 dir="auto">Versions</h2>

<ul dir="auto">
<li>Material-UI:  v0.15.0-beta.2</li>
<li>React: 15</li>
<li>Browser: Chrome 49</li>
</ul>
<ul class="contains-task-list">
<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" checked=""> I have searched the <a href="https://github.com/mui-org/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">In v0.x the Autocapitalize property would prevent mobile device keyboards from capitalizing the first letter - after upgrading to 1.x this does not seem to be the case</p>
<h2 dir="auto">Current Behavior</h2>

<p dir="auto">The Autocapitalize property seems to do nothing to prevent (on mobile devices especially) the first letter entered into the Textfield from being automatically capitalized (the device keyboard will SHIFT automatically when the Textfield is selected)</p>
<p dir="auto">I have tried every variant I can think of from autoCapitalize="none" (which is what I used in v0.x) to autoCapitalize="off" (which I've seen in various docs on the web) as well as writing the prop out all lowercase (which I believe is the raw html way to do it) and every variation in between.</p>
<h2 dir="auto">Context</h2>

<p dir="auto">We use the textfield component for our login form - we have case-sensitive usernames which are often not capitalized. I would prefer not to have to revert to v0.x for this one case as this was a working feature and seems like it would be needed for v1.x as well.</p>
