Bug 50438 [RCP] Progress view icon "area" shows even if setShowStatusLine(false) is called
Build: M6 If I call IWorkbenchWindowConfigurer.setShowStatusLine(false) in my WorkbenchAdvisor's preWindowOpen(IWorkbenchConfigurer) method the status line is hidden. BUT, the action with a tooltip of "Double click to open Progress View" which appears in the bottom left of the window still shows. The action is missing/can't find its icon so it just shows as empty screen space, but it shows over views that I put on the left side of the window.

IPlatformConfiguration platformConfiguration = BootLoader.getCurrentPlatformConfiguration();
					IPlatformConfiguration.IFeatureEntry feature = platformConfiguration.findConfiguredFeatureEntry(featureId);
					if (feature != null) {
						String pi = feature.getFeaturePluginIdentifier();
						if (pi != null) {
							Platform.getPlugin(pi);
						}
					}
				}
			}
	
			int wCount = configurer.getWorkbench().getWorkbenchWindowCount();
			for (int i = 0; i < welcomeFeatures.size(); i++) {
				AboutInfo newInfo = (AboutInfo) welcomeFeatures.get(i);
				String id = newInfo.getWelcomePerspectiveId();
				
				if (id == null || i >= wCount) {
					openWelcomeEditor(window, new WelcomeEditorInput(newInfo), id);
				}
			}
		}
