Hi all,

It is my understanding that it should be possible to have multiple 
metadata text tracks be loaded. I interpret that from the text below:

"If there are any text tracks in the media element's list of text tracks 
whose text track kind is metadata that correspond to track elements with 
a default attribute set whose text track mode is set to disabled, then 
set the text track mode of all such tracks to 
hidden<http://www.w3.org/html/wg/drafts/html/master/embedded-content-0.html#text-track-hidden>"

"There is no limit on the number of track elements whose kind attribute 
is in the metadata state and whose default attribute is specified."

and hidden says:
"Indicates that the text track is active, but that the user agent is not 
actively displaying the cues. If no attempt has yet been made to obtain 
the track's cues, the user agent will perform such an attempt 
momentarily. The user agent is maintaining a list of which cues are 
active, and events are being fired accordingly."

I tested that in Chrome Canary (v29.0.1537.0) but only the first 
metadata track seems to have its cues loaded. Is it a Chrome bug or have 
I misunderstood something?

Thanks,
Cyril
