Safari agrees: Facebook = Crackbook

Back when I was more addicted to Facebook, I added it to my bookmark bar with a title of “Crackbook”. Haw haw haw. Today, I noticed that Safari (nightly ricer super-beta) is placing the name of the bookmark into the title bar - and it stays there, even after the page has completed loading and should presumably have its own title attribute.

Also - this works for every bookmarked site I’ve got. Is this new/bug? I’ve never noticed before.
