I’m trying to clone an SVGRect object using structuredClone(), but am getting a DataCloneError: The object could not be cloned error — because, I guess, theSVGRect object isn’t serializable.

But what part of it wouldn’t be serializable?

Specifically, what I have is an SVG marker element with a viewBox attribute, and I assign that to a marker variable, and when I log `console.log(marker.viewBox.baseVal), the browser logs this:

[object SVGRect] {
  height: 10,
  width: 10,
  x: 0,
  y: 0

…but if I then do this: ```js let foo = structuredClone(marker.viewBox.baseVal); ``` …it fails, and the browser logs that *DataCloneError: The object could not be cloned* error

Web APIs are by default not serializable, even with DOMRect, which is as close to a plain object as it gets

Maybe it'd be worth it to try and identify such interfaces
