  <meta name="assert" content="Test checks that 'background-size: 100% 100%' applied for the html root element will make the background-image fill the padding-box of the document box. Since 'background-color' is 'transparent' and since 'background-repeat' is set to 'no-repeat', then only the padding-box of the document root box should be painted green and such padding-box should start at top-right corner of canvas because 'writing-mode' is set to 'vertical-rl'.">
