Why does DOMMatrix need to support it?  That's not true unless there's
legacy content relying on DOMMatrix (nee SVGMatrix) parsing it.

I oppose it because it's a blight of a syntax. :/  Unless someone has
a really good explanation, I'm assuming that it was originally allowed
by mistake in the first place, just an oversight in the grammar nobody
caught until it was too late.
