Andreas Kling	9c6999ecf2	LibWeb: Implement "NodeIterator pre-removing steps" ... These steps run when a node is about to be removed from its parent, and adjust the position of any live NodeIterators so that they don't point at a now-removed node. Note that while this commit implements what's in the DOM specification, the specification doesn't fully match what other browsers do.

Andreas Kling	fabcee016f	LibWeb: Add basic support for DOM's NodeIterator and NodeFilter ... This patch adds NodeIterator (created via Document.createNodeIterator()) which allows you to iterate through all the nodes in a subtree while filtering with a provided NodeFilter callback along the way. This first cut implements the full API, but does not yet handle nodes being removed from the document while referenced by the iterator. That will be done in a subsequent patch.	2022-03-09 16:43:00 +01:00
