(multipart/x-mixed-replace) doesn’t display at all when embedded in a page
http://code.google.com/p/chromium/issues/detail?id=238427

Version: 28.0.1499.0 canary
OS: Mac OS X 10.8.3 12D78
URL: http://mjpeg.sanford.io/

What steps will reproduce the problem?
1. Visit http://mjpeg.sanford.io/

What is the expected output? What do you see instead?
Expect: MJPEG animation to appear below the first line (“This page has an
mjpeg embedded in it:”), displaying a box with a number in it, counting up.
Observe: The image is not rendered at all. The page throbber spins as
though the page is loading something, but no frames of the image are ever
rendered.

When viewing http://mjpeg.sanford.io/count.mjpeg , the animation appears.
This URL just goes to the MJPEG animation directly, rather than embedding
it in the page. http://mjpeg.sanford.io/ just contains an <img> to
count.mjpeg.

Regression range:
http://build.chromium.org/f/chromium/perf/dashboard/ui/changelog.html?url=/trunk/src&range=194774%3A194830

Blink regression range:
http://build.chromium.org/f/chromium/perf/dashboard/ui/changelog_blink.html?url=/trunk&range=148559%3A148621

Because this works OK when viewing the MJPEG image directly but not when it
is embedded in a page, I suspect Blink. japhet r148560?

This is similar to bug 135337 although that bug appears to be fixed (and
should probably be marked fixed). I am using the test case from that bug.

This bug prevents me from being able to access an MJPEG-based camera that
monitors my home.
