When an out-of-flow-positioned element changes its display between block and
inline-block, then an incremental layout on the element's containing block lays
out the element through LayoutPositionedObjects, which skips laying out the
element's parent. The element's parent needs to relayout so that it calls
RenderBlockFlow::setStaticInlinePositionForChild with the out-of-flow-positioned
child, so that when it's laid out, its
RenderBox::computePositionedLogicalWidth/Height takes into account its new
inline/block position rather than its old block/inline position.
