Subject: [PATCH] ASSERTION FAILED: !m_invoking in CustomElementQueue::add() on
 tv.youtube.com https://bugs.webkit.org/show_bug.cgi?id=237977

Reviewed by Wenson Hsieh.

The assertion failure was caused by ARIA reflection attributes not having CEReactions.
Fixed the bug and filed a spec bug: https://github.com/w3c/aria/issues/1767
