Bisected builds all the way down to a seemingly innocuous change:
Repro'd on Safari/Mac, Chromium/Mac and Chromium/Linux... I'm wagering it affects all ports since it's seems to be MediaPlayer agnostic.
What was happening is that a call to m_player->seek(0) triggers an immediate call to HTMLMediaElement::mediaPlayerTimeChanged(), which clears the m_sentEndEvent flag.
Without clearing that flag, if someone changes the src inside of an ended event callback, m_sentEndEvent remains true even though the source has changed.
Haven't dug into a fix yet but I'm assuming we're not clearing m_sentEndEvent after changing the src.

Sure enough, it should be cleared in HTMLMediaElement::prepareForLoad where the other internal flags are reset.

Updated patch to mark test as slow.
Sadly the test does take ~6 seconds to run since the bug only repros if you don't seek.

Six seconds is too long for a layout test. silence.[wav,mpg,m4a,oga] is only one second long, can you use that instead?
