/**
 * Minimal WebVTT-markup-to-safe-DOM sanitizer for cue text handed to us as a
 * plain string (dash.js's manual-rendering `cueEnter` event). Real VTTCue
 * objects (hls.js) skip this entirely via the native, browser-trusted
 * VTTCue.getCueAsHTML() — this exists only for the string-based path, where
 * the source is a remote manifest/subtitle file the embedding page didn't
 * necessarily choose, so we don't trust it as pre-sanitized HTML the way
 * dash.js's own sample code assigns it straight to an element's markup.
 *
 * Keeps WebVTT's own formatting tags (b/i/u/ruby/rt/rp/span/br, plus the VTT
 * class-span tag `c`) and drops everything else — script/img/event-handler
 * attributes, href/src/style — by unwrapping disallowed elements (their TEXT
 * survives, just not the tag) rather than dropping their content outright.

/**
 * Karaoke cues carry the FULL final sentence after this delimiter so a renderer

 * min-width anchoring in CanvasRenderer). Only the part BEFORE it is ever
 * visible text — a renderer that doesn't do the anchoring must still cut it off,
 * or the marker and the whole upcoming sentence print on screen.
