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>.
