[Thomas Andersen]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20131205075310

Steps to reproduce:

1. Open Developer Tools / Network panel
2. Request this url: http://zippy.gfycat.com/ThreadbareCompetentEastrussiancoursinghounds.webm




Actual results:

The request is added to the list for a brief moment, then disappears from the list.


Expected results:

The request should be displayed in the list until a new document is requested.

As this video {http://media.w3.org/2010/05/sintel/trailer.webm} seems to create the expected result is seems like there is some special configuration on the gfycat server.

Firebug: Gives the expected result
Chrome DevTools Adds two requests (where the first says '(canceled)'

cURL command for further inspection,
curl -s -D - http://zippy.gfycat.com/ThreadbareCompetentEastrussiancoursinghounds.webm -o /dev/null

This happens when the webm file is loaded to the browser

You can see this by opening the Network tab and load the w3c video mentioned previously.
Watch the download progress bar in the video element. When the load is completed, the file disappears from the Network list.
