Bug 40559 [Preferences] Need to make the PreferencesPage accessible
We are currently using a CLabel for the preferences page to show the title or errors. This cannot be navigated to currently and needs to be replaced by something that can take focus.
bundles/org.eclipse.jface/src/org/eclipse/jface/preference/PreferenceDialog.java
if (pageMessage == null && pageErrorMessage == null)
			messageLabel.setFont(JFaceResources.getBannerFont());
		else
			messageLabel.setFont(JFaceResources.getDialogFont());
			
		if (pageMessage == null) {
			setMessage(currentPage.getTitle());
		} else {
			setMessage(pageMessage, pageMessageType);
		}
		setErrorMessage(pageErrorMessage);
