A lot of WhatsApp's features are enforced client-side, which means on Web they just break with DevTools. I've done some research into this (haven't published it) but also can't get Facebook's bug bounty report tool to work (whenever I create a facebook account it gets autobanned) so I haven't been able to report them either. I wonder if stuff like this would be eligible, I don't see why it wouldn't.
