            Bug ID: 266169
           Summary: [ManagedMSE] bufferedchange event isn't fired when
                    MediaSource::endOfStream is called
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jean-yves.avenard at apple.com

the bufferedchange event needs to be fired whenever the observable buffered range has changed.

Per MSE spec, when the MediaSource's readyState change to being "ended" the way the buffered change is calculated is changed [1]
"If readyState is "ended", then set the end time on the last range in source ranges to highest end time."

And so the buffered range changes when we call endOfStream() and the bufferedchange event should be fired then.
