Description:
------------
When calling `DOMChildNode::replaceWith()` on a given node,
If the node is also part of the argument list, PHP either throws a DOMException or just hangs indefinitely.

The bug is present at least in versions 8.0.12 and 8.1.0RC6

Test script:
---------------
// example 1
$doc = new DOMDocument();
$doc->appendChild($target = $doc->createElement('test'));
$target->replaceWith($target); // PHP Fatal error:  Uncaught DOMException: Not Found Error

// example 2
$doc = new DOMDocument();
$doc->appendChild($target = $doc->createElement('test'));
$target->replaceWith($target, 'foo'); // program hangs indefinitely

Expected result:
----------------
Both examples should be handled correctly, like browsers do.

I can confirm the reported issues.

Benjamin, could you have a look at this?

the issue is that when we boot a node with --replace_address_first_boot, the node maybe set with itself being a seed - in this case the node currently boots and may set its token on its own instead of taking the old node tokens.

The Element.replaceWith () method replaces this Element in the children list of its parent with a set of Node or string objects. String objects are inserted as equivalent Text nodes. A set of Node or string objects to replace. None ( undefined ). Thrown when the node cannot be inserted at the specified point in the hierarchy.

The childNodes property is a property of Node in Javascript and is used to return a Nodelist of child nodes.

If you are trying to replace more than one node at once, you have to be careful about iterating over the DOMNodeList. If the old node has a different name from the new node, it will be removed from the list once it has been replaced. Use a regressive loop: $newelement = $xml>createTextNode('Some new node!');

The childNodes property returns a NodeList containing the child nodes of the selected node If the selected node has no children, this property returns a NodeList containing no nodes.
