permanent."

Comment 1 Simon Pieters 2012-06-12 12:14:34 UTC 
We think the association between cue and track should be dropped when the cue is removed. It should be possible to move a cue between tracks and between videos. This would simplify our impl and remove restrictions for authors. At least for out-of-band cues. (If certain restrictions make sense for in-band cues, that's fine; we haven't implemented that yet and don't have a proposal for how they should behave exactly at this point.)
Comment 2 Simon Pieters 2012-06-19 14:58:12 UTC 
addCue and removeCue should never throw InvalidStateError (at least for out-of-band cues).

This bug was cloned to create bug 18235 as part of operation convergence.
Comment 4 Ian 'Hixie' Hickson 2012-09-11 22:46:49 UTC 
I originally did this so that the DOM API could just expose underlying data, so that you could use a standard library and expose its data without having to worry about mutating the library's data structures. Same with why the tracks weren't mutable.

But if it's easier the other way, sure... I removed the entire concept of cue association.
