	<rdar://problem/4002864> REGRESSION(125-146) getElementById in onload fails in a test case involving external resources

	Moved management of elementById hashtable from attach/detach to
	insertedIntoDocument/removedFromDocument, to avoid being thrown
	off by temporary detaches due to style recalcs.

        * khtml/xml/dom_elementimpl.cpp:
        (ElementImpl::insertedIntoDocument):
        (ElementImpl::removedFromDocument):
        (ElementImpl::attach):
        (ElementImpl::updateId):
        * khtml/xml/dom_elementimpl.h:

	Make sure that insertedIntoDocument is called before firing any
	DOM events.

        * khtml/xml/dom_nodeimpl.cpp:
        (NodeBaseImpl::dispatchChildInsertedEvents):
