    <p>I have a very simple page with a <code>&lt;video&gt;</code> tag and an email anchor link:<br> <a href="http://jsfiddle.net/6GquX/3/" rel="nofollow">http://jsfiddle.net/6GquX/3/</a></p> <p>Clicking the email link in Chrome (OS X 10.8 + Win7, 23.0.1271.97) invokes the <code>beforeunloadchange</code> event and causes the video to unload, which isn't the desired outcome.</p> <p>Curiously enough, if I let the video buffer a bit and then click the email link, the video keeps playing and doesn't unload.</p> <p>To my knowledge this only occurs in Chrome and I'm truly at a loss. Visiting any HTML5 video player site (videojs, flowplayer etc), starting a HTML5 video and then immediately simulating an email click with <code>document.location.href = "mailto:foo@bar.com"</code> in the dev console yields the same error. </p> <p>However, I'm inclined to think it's the way in which the video has been encoded as I'm unable to recreate the above with a video downloaded from YouTube's HTML5 player:<br> <a href="http://jsfiddle.net/6GquX/4/" rel="nofollow">http://jsfiddle.net/6GquX/4/</a> (<a href="http://www.youtube.com/embed/WkfgL5P3fw4?html5=1&amp;autoplay=1&amp;vq=medium" rel="nofollow">source</a>)</p> <p><strong>1. Is it possible that YouTube are encoding their videos in a particular way to combat this?</strong><br> <strong>2. Are there any strategies / hacks I can employ to get around this?</strong></p> <p><strong>Update:</strong></p> <p>The issue seems to be linked to the bitrate of the video. Re-encoding that flowplayer example above to 300kbps resolves the issue. (A 400kbps video still exhibits the same issue, not sure what the exact threshold is)</p> <p>300kbps example here: <a href="http://jsfiddle.net/6GquX/7/" rel="nofollow">http://jsfiddle.net/6GquX/7/</a></p> <p>Hopefully this will be resolved in a future version of Chrome.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
