Bug 281174 [UI] .active not set on widget
It appears we're no longer setting .active on a widget. I don't see the active selected tab being styled in the contacts demo, and I put breakpoints on both impls of the IStylineEngine.setClass() and neither fires.
bundles/org.eclipse.e4.ui.workbench.swt/src/org/eclipse/e4/ui/workbench/swt/internal/WorkbenchApplication.java
appContext.set(IResourceUtiltities.class.getName(),
							new ResourceUtility(Activator.getDefault()
									.getBundleAdmin()));
					Workbench wb = new Workbench(Activator.getDefault()
							.getInstanceLocation(), RegistryFactory
							.getRegistry(), Activator.getDefault()
							.getBundleAdmin(), appContext,
							new WorkbenchWindowHandler());
					wb.setWorkbenchModelURI(initialWorkbenchDefinitionInstance);
					if (cssURI != null) {
						CSSStylingSupport.initializeStyling(display, cssURI,
								cssResourcesURI, appContext);
					}
					wb.createUIFromModel();
					wb.run();
				} catch (ThreadDeath th) {
					throw th;
				} catch (Exception ex) {
					ex.printStackTrace();
				} catch (Error err) {
					err.printStackTrace();
				}
			}
		});
		return IApplication.EXIT_OK;
	}
	public void stop() {
	}
