Preserve siblings after <svg>

[TjeuKayim]

↪️ Pull Request

This pull-request fixes issue #10172 where an <svg> tag makes the next siblings disappear.

💻 Examples

Let's say you have the following HTML:

<svg><circle/></svg>
<p>aaa</p>
<p>bbb</p>

You would expect parcel build to keep the <p> elements, but it actually removed those elements. What adds to the confusion is that the bug did not happen with parcel serve and parcel build --no-optimize. So, it will be nice to have this bug fixed.

alternative approach:

            // Remember the original position
            let stub = arena.alloc(Node::new(NodeData::Document, 0));
            node.insert_after(stub);

            // Synthesize a fake document node to act as the root of the SVG.
            let document = arena.alloc(Node::new(NodeData::Document, 0));
            document.append(node);

            _ = options.minify_svg.into_jobs(OxvgKind::Html).run(
              &&*document,
              &oxvg_ast::visitor::Info::<crate::oxvg::Element>::new(arena),
            );

            // Reattach
            stub.insert_after(node);
            stub.detach();
