[Bug 21150] Changing duration while updating should fail

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21150

--- Comment #1 from Aaron Colwell <acolwell@chromium.org> ---
As far as I can tell, duration changes triggered by the JavaScript are already
blocked by pending appends.

- Step 3 on the duration setter algorithm prevents setting during
append.(https://dvcs.w3.org/hg/html-media/raw-file/default/media-source/media-source.html#widl-MediaSource-duration)

- The duration change triggered by endOfStream() is protected by Step 2 in that
algorithm.
(https://dvcs.w3.org/hg/html-media/raw-file/default/media-source/media-source.html#widl-MediaSource-endOfStream-void-EndOfStreamError-error)

I believe all other duration change calls are the result of algorithms run
during an append so I believe it should be ok. Am I missing something?
