Release Changelog 1.16.3

Release notes

Changelog pages could collapse to a single full-width column, with the content pressed against the site header, on sites using a performance plugin that removes unused CSS. The plugin’s own stylesheet was already protected, but WP Rocket also emptied WordPress’s global styles and the core columns and group styles, which is where the layout’s sizes and spacing come from. Those are now preserved on pages that show a changelog, and left alone everywhere else.
