Has anyone noticed that Safari is slow to autofill website suggestions lately? This seems to suspiciously coincide with the recent security update, which was rumoured to cause performance issues even if not reflected in synthetic benchmarks. I instinctively hit the return key like I'm used to, only to find Safari hasn't caught up with me yet. Gif below (might have to click on it).

Perhaps I am taking a simplistic interpretation of it, but isn't this a sort of operation that would normally benefit from prediction (which the issue affected)?
