When rendering the <html> element, the used values of CSS properties “writing-mode”, “direction”, and “text-orientation” on the <html> element are taken from the computed values of the <body> element, not from the <html> element’s own values. Consider setting these properties on the :root CSS pseudo-class. For more information see “The Principal Writing Mode” in https://www.w3.org/TR/css-writing-modes-3/#principal-flow
