Must have On mobile the link of the logo (to the home page), spans the entire width of the fixed navigation header, while the logo itself is only about half of it and displayed in the middle. This way there's no indication that the full top bar is a link, making it likely to be pressed unintentionally.
Additionally the other tap targets are superimposed on this link. So there is no space between the clickable area of both. Clicking just outside the search button or menu button, on any side of them, will result in navigating away from the page instead of opening the desired menu.
