--- Comment #1 from Simon Pieters <simonp@opera.com> 2012-05-23 12:26:18 UTC ---
Consider
var track = document.createElement('track');
track.src = 'foo';
When the track is created, the loading algorithm starts, which immediately
stores the track URL (which is the empty string) and runs the /download/ step
async. That step says to fire an 'error' event if track URL is empty and then
move on to the /monitoring/ step. Since it's async, it's racy as to whether the
script will have set .src yet or not.
This is clearly bogus. We should await a stable state before storing /URL/ and
starting the download.
Editorial comment: Since the same behavior should happen after the /monitoring/
step, these steps could be at the top of the /download/ so you don't need to
have the exact same steps repeated in two places in the algorithm.
