api.SVGTransform.matrix - in Chrome it doesn't return a `DOMMatrix`

[nimeratus]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The table says that Chrome fully supports the property, but in Chrome 143 it returns an SVGMatrix instead of a DOMMatrix and I think that counts as partial support

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet)

What did you expect to see?

It returns a DOMMatrix that has the toString() method that converts the matrix into CSS-like text

Did you test this? If so, how?

I added a transform="rotate(45)" property to an SVG <rect> element in the DevTools, then ran $0.transform.baseVal.consolidate().matrix.toString() in the console
