I've been saying this for years, and it gets down voted occasionally, but safari/webkit feels like the new IE6. I know Chrome is very bullish with adding extra features and is aggressively pushing some standards, but I've rarely had to write "workarounds" or hacks for Chrome when writing web-standard compliant code for other browsers, but I've had to frequently do it for Safari.

It's been a few years since I've had battle Safari quirks, one example that stuck with me from a couple of years ago is that LocalStorage is not available in private browsing mode. Other browsers just treat it as ephemeral/SessionStorage basically.

Also I remember our Sentry being _littered_ with random React internals throwing (it was like a couple of different things), but it was only ever iOS that had those issues.
