Force vertical scroll bars to appear even when not needed? #39
Description
As a user,
I want sites using the IATI design system to appear consistent when swapping quickly between them
so that I can not be distracted by page content shifting ~20px or so to the left.
At the moment, if you navigate between sites using the design system, and one doesn't need vertical scrolls but one does, all the common content shifts to the right on the page without the scrollbars, which is distracting/annoying when navigating quickly between, e.g., the Validator and the Validator Docs site.
If we forced vertical scroll bars to always appear, even when not needed, the header / footer content would appear in a consistent place across all sites.
