That's how SVG animated value objects work. I'm not a great fan of it, since it means DOMRect's attributes can all throw, which is confusing in the situations where you have a mutable DOMRect. But it's OK I guess. If we're making DOMRect mutable we have to decide what happens when its members are modified, since there are options. For example, when "width" is modified one of "left" and "right" must also change, and we have to specify which one, or else specify that "width" is actually readonly. I think the simplest thing to specify is that "right" and "bottom" are readonly and the other attributes are mutable and mutating them affects "right"/"bottom". Is it sane to allow modification of a DOMRect that was returned by e.g. > getBoundingClientRect()? Yes.
