>+        The release assertion was hit because we were not catching & re-throwing the exception thrown by DOM API
>+        before trying to execute custom elements reactions in ~CustomElementReactionStack as specified here:
>+        https://html.spec.whatwg.org/multipage/custom-elements.html#cereactions
>+        Fixed the bug by capturing the exception and re-throwing the exception as specified.
