> `Uint8Array.prototype.isPrototypeOf` and `instanceof Uint8Array` do not work across realms (frames, Node.js VM, etc).

That sounds like a bug in those implementations.

That’s a reasonable intuition, but it’s not a bug. Global scopes are isolated between realms by design, and that applies to built-ins as well as their prototype chains.
