Currently in the site module, horizontal overflow is prevented with overflow: hidden. This prevents the use of position: sticky, and removing it means that some elements will force the width to be wider than the viewport.
The reason for the overflow: hidden is given in a comment: "Resolves issue with
elements forcing full width". It actually happens with many other elements, mainly media and flex layouts. The reason it happens is because a grid cell will not shrink past its contents' minimum width, and the solution is to set the min-width of the grid items to 0.
