seeking to 0 when currentTime is already 0 doesn't fire the `seeked` event which isn't per spec (note that chrome has the same issue). 
The spec does NOT have an early-abort for seeking to the current position. The seek algorithm always runs through and 
fires seeking/seeked. The only early-aborts are for readyState == HAVE_NOTHING and no seekable ranges.
