 // certain tree walks (e.g. layout()). The rule is that anything that
 // cares about containing blocks should skip the out-of-flow elements
 // in the normal tree walk and do an optional follow-up pass for them
 // using LayoutBlock::positionedObjects().
 // Not doing so will result in passing the wrong containing
 // block as tree walks will always pass the parent as the
 // containing block.
 //
 // Sample code of how to handle positioned objects in LayoutBlock:
 //
-// for (LayoutObject* child = firstChild(); child; child = child->nextSibling()) {
+// for (LayoutObject* child = firstChild(); child; child = child->nextSibling())
+// {
 //     if (child->isOutOfFlowPositioned())
 //         continue;
 //
 //     // Handle normal flow children.
 //     ...
 // }
 // for (LayoutBox* positionedObject : positionedObjects()) {
 //     // Handle out-of-flow positioned objects.
 //     ...
 // }
