I'm not sure I understand the question. 

The difficulty is entirely on iPad devices, since that's the only place we see this bug. Other devices (e.g. Android, Chrome on macOS) will consistently send pointer events no matter what happens.

So, only on iPad, I would need to implement and support two simultaneous paths to receive events: (1) through pointer events, (2) via traditional mouse events.

Because (1) could silently stop working at any time, I'd need to somehow seamlessly cut over to (2) as soon as those events start appearing. But since mouse events don't support things like multitouch, it would be at best a fallback mechanism. And after that fallback, the only way to restore full functionality is to reload the web view, which is a terrible user experience.
