Storing an ArrayBuffer doesn't get retrigger when setting a new value

[dumconstantin]

Producer b is only called once:

const a: producer = ({ foo = update.value }) => {
 const int32 = new Int32Array(2);
 int32[0] = 42;
 foo.set(int32);
 setTimeout(() => {
 int32[1] = 43;
 foo.set(int32);
 });
};
const b: producer = ({ foo = observe.value}) => {
 console.log("foo is", foo);
};

But first setting the value to null and then async setting it to the next array buffer value, the b producer is called twice as it should:

const a: producer = ({ foo = update.value }) => {
 const int32 = new Int32Array(2);
 int32[0] = 42;
 foo.set(int32);
 setTimeout(() => {
 int32[1] = 43;
 foo.set(null);
 setTimeout(() => {
 foo.set(int32);
 })
 });
};

This has to do with the comparison logic as I've tested with different values in the buffer/different buffers and it still doesn't retrigger on update.
