Even if that's an edge case, it's why having only one engine is pathological. Maybe Safari iOS works fine for you. Not for me. I don't want rationalization on why it's not Apple's fault, or somehow not Safari's fault, or "they'll fix it one day", or "I'm doing it wrong", or all the fanboy-talk that sounds like the enabling relative of an alcoholic. Don't care. I should be able to switch for even the most frivolous reason. Maybe I don't like that it doesn't render every website in pink.
It's like having only one type of chocolate in existence. This was never normal.
