           Summary: Redundant requirements to seek when duration changes
           Product: HTML WG
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Media Source Extensions
        AssignedTo: adrianba@microsoft.com
        ReportedBy: philipj@opera.com

http://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html#source-buffer-duration-updates

"If the current playback position is beyond the new duration, then update
HTMLMediaElement.currentTime to the new duration and run the seeking
algorithm."

http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html#durationChange

"If the duration is changed such that the current playback position ends up
being greater than the time of the end of the media resource, then the user
agent must also seek the to the time of the end of the media resource."

It would be possible to just remove the redundant requirement from MSE, but
referencing HTML in a note for clarity is also fine.

(Also, the quoted text looks a lot like an implementation requirement in what
is actually a non-normative overview.)
