WizardPageSupport does not dispose DataBindingContext

[basilevs]

Following test fails in org.eclipse.core.databinding 1.13.300
Paste it into WizardPageSupportTest.java to reproduce.

public class org.eclipse.jface.tests.databinding.wizard.WizardPageSupportTest extends AbstractSWTTestCase {
	@Test
	public void testDispose() {
		AtomicBoolean disposedAtomic = new AtomicBoolean(false);
		IWizardPage page = new WizardPage("Page") {
			@Override
			public void createControl(Composite parent) {
				setControl(parent);
				DataBindingContext dbc = new DataBindingContext();
				dbc.addValidationStatusProvider(new ValidationStatusProvider() {

					@Override
					public IObservableValue<IStatus> getValidationStatus() {
						return new ConstantObservableValue(dbc.getValidationRealm(), Status.OK_STATUS, IStatus.class);
					}

					@Override
					public IObservableList<IObservable> getTargets() {
						return Observables.emptyObservableList(dbc.getValidationRealm());
					}

					@Override
					public IObservableList<IObservable> getModels() {
						return Observables.emptyObservableList(dbc.getValidationRealm());
					}

					@Override
					public void dispose() {
						disposedAtomic.set(true);
						super.dispose();
					}
				});
				WizardPageSupport.create(this, dbc); // Should dispose all status providers when wizard is closed
			}
		};
		loadWizardPage(page);
		assertTrue(disposedAtomic.get());
	}

}

WizardPageSupport.create() documentation does not mention that DBC is not disposed and no snippets from examples dispose the DBC explicitly.
