           Summary: video doesn't display when <video> size is same as
                    video resource size
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: wjia at chromium.org


There is no video display when the following sequence is done:
1. The page has
<video width="640" height="480" id="videoView" autoplay="autoplay"></video> 

2. Later on, JS update <video>'s src as
document.getElementById("videoView").src = VGA.mp4
where VGA.mp4 has video frame size as 640x480.

Scaling the browser window enables video display.

It appears that RenderVideo doesn't request re-layout since poster frame has same width/height as video resource.
