Validation messages are presented at the top of a document when there is invalid entry in a form. The accessibility object for these is only created once, and either added or removed from the root object's children depending on whether it's currently visible. This can lead to a situation where it's marked dirty and the serializer tries to use it, even when it's not currently part of the tree. This CL removes the requirement for it to have a parent, in order to avoid DCHECK()s that require all objects but the root to have a parent, and repairs missing parents. Another solution could be to detach and remove the validation message object (validation_message_axid_), when it is not in use, and create a new one each time one is needed.
