offsetParent, offsetLeft & offsetTop should be on Element or Node instead of HTMLElement

[jogibear9988]

What is the issue with the HTML Standard?

I'm creating a Designer Application, and for this I need to calculate the complete transformation of an element (and all it's parents). For HTMLElements I can get the x&y coordinates wich is cause by the positioning logic via offsetLeft & top property. But this is not possible for other types (like SVGElement or MathMLElement).

But these elments are positioned inside of a container too, so they also have these coordinates.

So these properties should be on Element, or maybe they should be on Node, cause also a TextNode could be positioned inside of a Container.

The HTML Standard does not define these properties; please open an issue on https://github.com/w3c/csswg-drafts/ instead.
