When closed captions, audio descriptions, sign languages are presented by
associated media or timed text resources, the playback will often need to be
automatically, temporarily paused to present lengthy descriptions/captions
(e.g., extended descriptions). This "paused" state should have a different mode
from the normal paused state so that clicking on the play/pause button does not
cause unexpected behaviors.

That is, for example, the media.pausedInternally attribute and
media.pauseInternally() method are needed in addition to the normal
media.paused attribute and media.pause() method, where pauseInternally()
pauses/resumes the playback and changes the value of the .pausedInternally
attribute (only when .paused = false) but does not affect the value of the
normal .paused attribute, i.e., the state of play/pause button.
