<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Editor: Allow theme.json to take precedence in setting the root level element's reset margin value.
Any margin added to the root element via `theme.json` is overwritten by a CSS reset margin value provided by the Gutenberg Plugin.
This commit makes `theme.json` setting take precedence by generating the global styles body reset prior to processing the theme.json.
