Full-screen issues and subtitle non-rendering in Edge and Firefox.

Created by: TobbeMobiTV

In testing the new HTML rendering of TTML we have found that

  1. Chrome: Works fine in both window and full-screen mode
  2. Safari: Works fine in both window and full-screen mode
  3. IE11: Works fine in window mode. Full-screen doesn't work at all (it seems overlay not supported).
  4. Edge: Native or HTML-rendered are not working unless IE11 mode is set (uses addTextTrack API). Full-screen doesn't work
  5. Firefox (v42): Native text tracks do not work unless IE11 mode is set (uses addTextTrack API). However, onenter() onexit() are not called on the cues so HTML-rendering does not work.

The new control bar in the reference player seems to have similar issues with full-screen. In addition, on Safari the native control bar appears in full-screen, so it should be disabled.

What should we try to fix in Release 1.5?
