[Layout][Grid] Mitigate incorrect baseline for vertical-lr flex/grid boxes.
https://bugs.webkit.org/show_bug.cgi?id=296443
<rdar://156628380>
Reviewed by Alan Baradlay.
Inline layout currently performs an unnecessary coordinate flip in
InlineDisplayContentBuilder::mapInlineRectLogicalToVisual()
for vertical-lr content.
This is not necessary for boxes that provide the correct coordinates
and baselines, which are then broken by this flip.
This change introduces a temporary fix in
LayoutIntegrationGeometryUpdate::baselineForBox()
by performing another flip for line-inverted writing modes. This ensures
that the baselines computed by the LayoutIntegrationGeometryUpdate will
allow the content to be rendered correctly.
