Chrome has them too :)

Yeah, because chrome is required to use -safari- webkit too, apple won't allow alternative browsers on the app store.

Except in the EU, but they don't allow it globally so no sane company is going to invest time into building a browser for iOS while apple is intentionally region-locking the ability to install them.

So yeah, on iOS, rendering bugs on Chrome are quite often apple's fault, and the Chrome team can't fix em.
