Bug description

When opening modals, we lock scrolling on the screen and hide the scrollbar.

This works fine on larger screens. But the scroll bar is already hidden on mobiles (unless you are actively scrolling).

This is creating a layout shift when a modal is closed, demonstrated in this video:

Additional Comments

We hide the the scrollbar by applying a Tailwind p-4 utility class to the document body here:

This likely only needs to be applied to screens above Tailwinds sm breakpoint. So changing to sm:p-4 might fix it.
