fix: Elements added inside an svg element are not visible

[petlyh]

Description

Elements that are added inside an svg element after the initial page load are not visible.

Steps To Reproduce

1. Create a StatefulComponent that mutates state in such a way that new elements are added inside an svg element when it is rebuilt.
2. Build and open the webpage.
3. Observe that the new elements are not visible.

Minimal reproducible example

https://github.com/schultek/jaspr/assets/88139840/4a9fb7b0-ec05-4cb8-a0f3-a6717d15a9fb ```dart import 'package:jaspr/jaspr.dart'; class App extends StatefulComponent { const App(); @override State createState() => AppState(); } class AppState extends State { int count = 5; void setCount(int newCount) { setState(() { count = newCount; }); } @override Iterable build(BuildContext context) sync* { yield button([text("Add")], events: {"click": (_) => setCount(count + 1)}); yield button([text("Remove")], events: {"click": (_) => setCount(count - 1)}); yield p([text("Not inside SVG:")]); yield _box( Iterable.generate(count).map((i) => p([text("$i")])).toList()); yield p([text("Inside SVG:")]); yield _box([ svg( Iterable.generate(count) .map((i) => DomComponent( tag: "text", child: text(i.toString()), attributes: {"y": ((i + 1) * 35).toString()})) .toList(), height: Unit.pixels((count + 1) * 35)) ]); } } Component _box(List children) => div(children, styles: const Styles.box( border: Border.all( BorderSide.solid(color: Colors.black, width: Unit.pixels(1))))); ```

Expected Behavior

The new elements are shown when the component is rebuilt.

Actual Behavior

The new elements are not rendered despite being added to the DOM and appearing in the browser's inspector panel.

Additional Context

Happens on both Firefox and Chrome.
