Renders a cue's text payload as safe HTML. Text is escaped (so it can't
inject nodes); newlines become <br>; and WebVTT cue tags are converted:
<c.foo>→<span class="foo">, <i>/<b>/<u>/<ruby>/<rt> pass through,
<v Name>→<span title>, <lang xx>→<span lang>, timestamp tags are
dropped. Class-based styling requires matching app CSS (STYLE blocks in the
VTT are not applied).
