We refer to this statement:
"there must not be two track element children of the same media element whose
kind attributes are in the same state, whose srclang attributes are both
missing or have values that represent the same language, and whose label
attributes are again both missing or both have the same value."

Comment_4 is the key comment.

It was unclear to John and me what happens with an invalid specification of
several tracks of the same kind/src/label combination.

The issue is that dealing with the invalid case doesn't really need to be in
the spec, but that it would still be nice if all browsers behaved the same in
such an invalid situation and not dropped any tracks on the floor. In
particular, they need to remain available in the media element's TextTrack[]
list.

Might be worth a small comment. Though if that's clear to browser developers,
it's ok to have clarified this understanding for Web developers.
