IOS9 WKWebView html5 video no playback button
<p>I'm using WKWebView to display html5 video element. When view is loaded initially there is play button (big round button).  If you press it built-in video fullscreen  controller is displayed and video starts playing.</p>

<p>While video is playing press "Done" button:<br>
1. fullscreen controller collapses and I see my webview<br>
2. but <strong>there is no play button anymore</strong> (so I can't start playing video again)</p>

<p>If you first pause video and that press "Done", or watch video to the end and then press "Done" everything is fine.</p>

<p>Works on IOS8 without issues.</p>

<p>Is it IOS9 bug, or I have something configured wrong?
What workarounds are possible?</p>

<p>Here is html that is loaded into webview:</p>

<pre><code>@"&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;meta name=""viewport"" content=""width=device-width, initial-scale=1, user-scalable=no""&gt;
    &lt;style&gt;
        html, body {{
            margin: 0;
            padding: 0;
            background-color: #000;
        }}
        video {{
            background-color: #000;
            width: 100%;
            height: auto;
            max-height: 100%;
            margin: auto;
            top: 0;
            left: 0;
            bottom: 0;
            right: 0;
            position: absolute;
        }}
    &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;video poster=""{0}""&gt;&lt;source src=""{1}"" /&gt;&lt;/video&gt;
&lt;/body&gt;
&lt;/html&gt;";
</code></pre>
