Any specific reason why this depends on bug 1471947?
Because websites are broken if only custom elements or shadow DOM is enabled. They need to be both enabled or neither.

Actually, this still needs updating on https://platform-status.mozilla.org/#custom-elements and https://platform-status.mozilla.org/#shadow-dom. See https://github.com/mozilla/platform-status/pull/545 for details.
html5test.com still shows Custom elements as not supported even on today's 63.0b3.
html5test.com seems to be testing v0 Custom Element API. That is blink only API, not in any specification anymore.
(In reply to rniestroj from comment #6) > html5test.com still shows Custom elements as not supported even on today’s > 63.0b3. It will show up on https://html5test.com once they update to HTML5test version 9 (which is currently available at https://alpha.html5test.com/)
