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.

if (error != null) {
						Display.getDefault().asyncExec(new Runnable() {
							public void run() {
								try {
									IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
									if (window != null && !window.getShell().isDisposed()) { 
										IWorkbenchPage page = window.getActivePage();
										if (page != null) {
											IViewPart tasksView= page.findView(IPageLayout.ID_PROBLEM_VIEW);
											if(tasksView == null) {
												IWorkbenchPart activePart= page.getActivePart();
												page.showView(IPageLayout.ID_PROBLEM_VIEW);
												
												page.activate(activePart);
											} else {
												page.bringToTop(tasksView);
											}
										}
									}
								} catch (PartInitException e) {
									IDEWorkbenchPlugin.log("Error bringing problem view to front", e.getStatus()); 
								}
							}
						});
					}
				}
			}
		};
