with the RenderAbove WindowMode. This mode will ensure child windows always draw above their parents, even when focus is lost. RenderAbove modals are automatically themed the same as the old ToolWindows. Fixes ToolWindows rendering above ALL normal windows, regardless of parent. We can't rely on WindowType to create these sort of effects because of WindowManager's strict display hierarchy.
