  Log Message:
  -----------
  Thread safety assertion failure in InternalObserverMap::visitAdditionalChildren
https://bugs.webkit.org/show_bug.cgi?id=284391
rdar://141232149

Reviewed by Chris Dumez.

InternalObserverMap::visitAdditionalChildren should not ref/deref objects that
are single-threaded ref counted like Subscriber and MapperCallback since this
function gets called concurrently to the main thread.
