This sounds more like Safari's newer behaviour, which sounds good in theory but in Safari's case where it can't be turned off, it breaks things in practice. This seems like a good solution for people that are aware of what's happening enough to pay attention and disable it when something is not working as expected, but makes a bad default for the typical user.
