Test HTML5 application

Calling sourceBuffer.abort() from a test HTML5 application during seeking freezes playout. Test scenario works properly in Safari, Chrome and Firefox, but fails in MiniBrowser and our proprietary component which is also based on WebKitGTK.

Steps to reproduce the bug:
* Unzip the attached archive.
* Host and load mse.html - MSE video should start playing.
* Wait for approximately 10 seconds - seeking will be triggered.

Expected result: seek operation succeeds, video playout continues.
Actual result: video playout freezes.
