Huge refactoring; browser compatibility; aesthetic changes; when dialog is open ignore globa keys; playback speed support; per play shortcut keys; scrubbing via captions/transcript/description; responsive player flow; tons of bug fixes.
Transcript language select now displays 'Unknown' and disabled when there is at least one track, but no tracks with srclang
attributes; tooltips now refocus their originating button when closed by ESC or tabbing off; aria-polite seek bar region now
only updates when tracking, using a seek feature, or having the seek head focused; caption title is now simply 'Captions'
when there are multiple caption options
Merging.
