When the component contains svg elements then it throws error on rerender:

Uncaught (in promise) Error: Could not clone element

Thank you for this! Kind of a pain that we need to deal with the union type. As best I can tell, DOM nodes will be either HTMLElement or SVGElement: I think there aren't more types we're missing.
