public class LayoutManagerIE8
extends LayoutManager

Alternative MeasuredSize storage for IE8. Storing any information in a DOM element in IE8 seems to make the browser think the element has changed in a way that requires a reflow. To work around that, the MeasureData is instead stored in Map for IE8. This implementation is injected for IE8 by a replace-with definition in the GWT module.
