RenderFlexibleBox::layoutAndPlaceChildren has a FIXME that stems from a Blink merge (https://bugs.webkit.org/show_bug.cgi?id=168657). It is not clear what it refers to, but I believe it is the following from the CSS Align 3 spec: For the purposes of finding the baselines of a box, it and all its in-flow descendants with a scrolling mechanism (see the overflow property) must be considered as if scrolled to their initial scroll position. Furthermore, if, in the case of a scroll container box, the resulting position of a first/last baseline is past a box’s end/start border edge, its position is clamped to that border edge. https://www.w3.org/TR/css-align-3/#baseline-rules Should figure out if this is actually what it refers to or if it is some other issue
