[Bug 24860] When can user agents honor the user preferences for automatic text track selection

https://www.w3.org/Bugs/Public/show_bug.cgi?id=24860

--- Comment #4 from Jon Piesing (HbbTV) <hbbtvjon@gmail.com> ---
The URL given doesn't work. Is this a reference to section 4.7.10.13 "User
interface" and the controls attribute?

If it's a reference to the controls attribute then that has numerous issues in
a TV environment. TV apps generally do not include the controls attribute to
avoid those issues and the subtitle key would need to work when that attribute
is not present.

>In particular, when toggling subtitles on/off, the browser will set the "text track mode" of all subtitles tracks to "disabled" and thus in the "time marches on" algorithm, all disabled tracks cues will not be shown.

That is great but doesn't address the point of whether a browser mechanism to
control subtitles is permitted when the controls attribute is not present. If
the contrbutors to this part of the spec believe that this is supposed to be
permitted then it should be made clearer in the spec.
