This isn't just an iOS bug. The affected CSS property is just not available on most platforms.

Sinfe I do not have access to any apple hardware, I tried turning on the experimental web features in Chrome Canary on my phone and it managed to freeze Android as well. The Chrome browser crashed on Windows with this setting on. Microsoft Edge, the only browser other than Safari to have support this property without messing with config, just showed a generic "this page can not be displayed" message.

I think this problem affects the entire WebKit/Blink code base, the only reason the crashes are not being detected on other platforms is that most browsers just don't support this feature yet.
