Summary fixed positioned elements not rendered in RTL/vertical-rl

css/css-anchor-position/anchor-scroll-position-try-007.html seems to fully pass... except that the anchor positioned element isn't rendered at all. anchor() functions still resolve to the correct value though. It looks to be a vertical-rl issue - if the html { writing-mode: vertical-rl; } is removed, then the anchored element does render. Maybe a repaint issue?
