Description

Research direction
Start by reproducing the .vtt subtitle failure in IE11 against the 4.12.x branch, then compare it with 4.10.x and 4.11.x, where subtitles reportedly work. Check the existing subtitle or caption entry points and browser-specific behavior; done means captions work in IE11 without regressing Chrome, Opera, or Firefox.
