This is a really tricky issue to deal with - we had that problem ever
since a discussion around cue points from as long ago as 2007 (!), see
http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-October/012860.html
. I think we should avoid cue points if at all possible (see reasons
in the bug and in the years of discussion around HTML).

It has been applied to HTML5.1 and will be applied to HTML5 CR.
