Mobile navigation width is offset by scrollbar #5725
Description
On browsers that support ::webkit-scrollbar, the navigation width is offset by the width of the scrollbar, hence not exactly 100% of the overflowing parent.
In other browsers (e.g. Firefox, iOS browsers), the navigation width is correctly set to 100% of the overflowing parent, and with uneven padding on the parent, the nav looks like it's overflowing.
