Specification: http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html Multipage: http://www.whatwg.org/C#text-track-model Complete: http://www.whatwg.org/c#text-track-model Comment: "Otherwise, the text track cue line position is the special value auto; if the text track cue snap-to-lines flag of the text track cue is not set, the text track cue computed line position is the value 100" - I think auto and unset snap-to-lines shouldn't be possible Posted from: 85.227.154.145 by simonp@opera.com User agent: Opera/9.80 (Macintosh; Intel Mac OS X 10.7.3; U; en) Presto/2.10.229 Version/11.62
This bug was cloned to create bug 18183 as part of operation convergence.
Can you elaborate?
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html#dom-texttrackcue-snaptolines allows setting snap-to-lines to false even if line is auto or negative or greater than 100. The snapToLines setter should check the value of line before updating the value. If that is changed, you can strike "if the text track cue snap-to-lines flag of the text track cue is not set, the text track cue computed line position is the value 100; otherwise," since that can't happen when line is auto. (It's not possible to get auto and snap-to-lines unset in the WebVTT syntax.)
