QQStyleKitDebug previously printed property paths under the assumption that nested property groups followed the same parent–child hierarchy as they are written in the style. After a recent optimization in QQStyleKitPropertyGroup, this assumption is no longer valid. As part of that optimization, all property groups now have the root QQStyleKitControlProperties as their parent in order to avoid unnecessary hierarchy traversals. This change broke the logic used to reconstruct property paths for debugging. This patch introduces QQStyleKitPropertyGroup::pathToString(), which reconstructs a property path in the same order as it is written in the style. While this functionality may also enable future optimizations, it is currently used to restore correct and readable debug output.
