[BUGFIX beta] preventDefault in SVG LinkTo

[Recour]

When wrapping LinkTo in an SVG element, the click event.currentTarget is not an instanceof HTMLAnchorElement but of SVGAElement. preventDefault is only triggered when isSelf, but it needs to be triggered when wrapped inside an SVG as well, otherwise clicking the element causes a reload.

Fix for #19891

Question: Is it valid HTML to put a link inside of an SVG? Typically it should be the other way around. Additionally, an SVG is not eligible to receive interactions (but a link is).
