Yes this is minor, but seems correct. And we do already use a pointer for the menu items in the Browse dropdown.

Also, after a quick survey of several websites shows that a pointer 👆🏼 is indeed more common for buttons and icons—just look here on GitHub!

I'm +1 by code review.

Edit: tested patch for good measure and it works as expected.
