Missing / Incorrect Definition
DOMMatrix and DOMMatrixReadonly constructors are typed as accepting only number[] but they also accept TypedArrays in all browsers.
The following code works in all browsers:
Sample Code
new DOMMatrix(new Float32Array(16))

The MDN documentation doesn't really mention this detail, and the spec mentions a "sequence" which to me isn't very specific. Isn't a TypedArray a "sequence of numbers"?
Perhaps the type should probably be ArrayLike<number>.
