As I was doing some tests on the new `Header` I noticed that if a user resized the window while the mobile nav header was acitve, the moible nav header would still be open. This diff fixes this problem by adding a resize event listener that checks if the window width is more than 848px (the breakpoint that @ted and I determined earlier) and if the window is ever bigger than 848px sets the `showMobileNav` state to false Depends on D7869
