Yes, on desktop. I still think it’s a small bug/glitch on desktop, because why shouldn’t the panel toggle on click, just as with the other two panels.
On mobile, I didn’t intend to report a bug. But just ask what’s the ux idea on mobile. The hamburger and the user icons open a slide-in-panel. It can be swiped back and my location on the page didn’t change. Search directs to a new url and I’d need to navigate away from it. To me, it would make the ux more predictable if there’d be a consistent result for all three icons as well. E.g. they could just all slide in from the left.
