In the introductory paragraph of the Time-dimensional pseudo-classes
chapter, the phrase "time-dimensional canvas" is used:

"These pseudo-classes classify elements with respect to the
currently-displayed or active position in a time-dimensional canvas,
such as during speech rendering of an HTML document."

I (and, from twitter replies, other people) have no idea what this
actually means.  I suggest rewording it in more explicit terms, and
referring to the primary existing example of their use: captions in a
video.  Something like:

"These pseudo-classes classify elements with respect to the
currently-displayed or active position in some timeline, such as
during speech rendering of an HTML document, or during the display of
an HTML video using WebVTT to render karaoke subtitles."
