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. 68063 2 zcorpan 2012-05-23 17:38:48 +0000 (In reply to comment #1) > Consider > > var track = document.createElement('track'); > track.src = 'foo'; Make that: var track = document.createElement('track'); track.mode = 'showing'; track.src = 'foo'; 68553 3 zcorpan 2012-06-04 05:21:34 +0000 *** Bug 17156 has been marked as a duplicate of this bug. *** 70891 4 contributor 2012-07-18 17:42:03 +0000 This bug was cloned to create bug 18212 as part of operation convergence.
