To be fair, he's completely right. I have a lot of experience with IE6 and safari on iOS, and while IE6 was bad and did weird shit, Safari is much worse. It's amazing that things can work in any browser, without ever even thinking about it, but then on Safari you get weird behaviour, straight up rendering bugs because of some weird race conditions with the engine or even crashes.

The latest issue that I've noticed yesterday is the button nav bar on the screen when running PWAs. The button is over the bottom navbar of the PWA, and despite apple themselves coming up with the API to inform the browser about safe display areas, it doesn't work in PWAs on iOS. PWA mode on iOS != non PWA on iOS. They often behave completely different and you often have to use JS for basic things to work, like clicking a link(yup, this was a thing for years).
