Re: Lack of removeTextTrack?

Karl, thanks for the investigation. I was concentrating on the fact that it
wasn't in the spec., hence I never checked the individial browser's bug
reports.

I did perform a search on the mailing list however, but it came back with
nothing which is odd as you clearly show that isn't the case. I must have
made a mistake somehow, sorry, I wasn't being lazy!

Not sure about Mozilla's "it wouldn't be good to be able to remove
TextTracks that have been sourced from the media resource or from
TrackElement for that matter", with no explanation as to WHY it wouldn't be
good.

https://www.w3.org/Search/Mail/Public/search?keywords=removetexttrack
reports "As per discussion of cloned by in WHATWG, there is no need for
this feature at this time, so marking WONTFIX for now.", where/how might
one find more information on this discussion? I cannot find it.

I am only asking about this as I needed removeTextTrack the other day and
was surprised to find that it doesn't exist, even for completeness sake
(weak argument I know).
