The upshot: I struggle to imagine a process whereby an obscure English children’s game somehow inspired gestural customs in Georgia, Egypt, Russia, and Iran within less than a century. It seems more reasonable to me that these customs might instead originate in an ancient Mediterranean tradition of apotropaic magic, or charms intended to combat bad luck.
The V3 approach obliterates this race condition by hooking addSourceBuffer at the MediaSource.prototype level, I intercept the creation of every SourceBuffer. The moment a buffer is created and returned, I immediately install a hooked appendBuffer directly on that specific instance; before any page code can even see the instance, let alone cache a reference to its methods. The hooked appendBuffer is installed as an own property of the instance, which takes precedence over the prototype chain. There is no window for fermaw to cache the original. The hook is always first.
