I mean they failed css2 (exists since 2000) features that exists since forever and bugged even before the divergence. Those features works on literally everyone includes ie 11 except safari and even against the spec apple provided itself. They never got fixed. There are tons of obvious ancient bugs on the safari exists are since day one and seems no one it fixing it(even they confirm it is a bug on their bug tracking site). Its supports site is a total joke. This is also what I believe why the divergence happened. If a bug exists in half of browsers and spec don't really defined it, then it's my fault. If a bug exists in exactly one browser and behaved contrary to the spec, then it's browsers fault. And there are way too many to count on safari.
