This patch changes the Ivy `DebugElement` code to always read style and class values directly from the native element instead of reading them through the styling contexts. The reason for this change is because Ivy does not make use of a debug renderer and will therefore not have access to any classes/styles applied directly through the renderer (unless it reads the values directly from the element).
