Once https://bugs.webkit.org/show_bug.cgi?id=224224 lands, the /css/css-writing-modes/sizing-orthog-vrl-in-htb-013.xht and /css/cssom-view/cssom-getBoundingClientRect-vertical-rl.html WPTs will start failing. These tests need adjusting to avoid making assumptions about scrollbar position.
Fixing these upstream at https://github.com/web-platform-tests/wpt/pull/28425.
