It still works, you can click on something non-focusable like the background or hit Esc and still get the "first page" thing. Like a touch interface.
Funny that's already so intuitive for how touch interfaces works, I guess it would take maybe a week to change but forever to decide what specifically precisely should be done, so if it's not something epoch-defining, world-changing and comparable to search itself, then maybe just leave it, lest you make a mistake that half the customers likes.
