--- Comment #13 from Jonas Sicking <jonas@sicking.cc> ---
FWIW, at mozilla we've thought of removing this function as a performance
optimization. I.e. that the fallback code path that sites hopefully provide is
likely faster than calling the function.
I.e. we expected code like
if (a.isSameNode ? a.isSameNode(b) : a === b) {
// a is same as b
}
or
if (!Node.prototype.isSameNode) {
Node.prototype.isSameNode = function(other) { return this === other; };
}
I don't recall if we made that assumption based on code in the wild or not.
