| * Description: Closing a tab in a part stack does not hide toolbar line, if toolbar was below tabs line. |
| * |
| * <ol> |
| * <li>Open many views in the same part stack, so that the toolbar of the last view is rendered on a line below the tabs.</li> |
| * <li>Close views in the that part stack, until the toolbar of the current view is rendered in the same line as the tabs.</li> |
| * </ol> |
| * Expected results: The line in which the toolbar was rendered vanishes on step 2. |
| * Actual results: The line remains until a resize is done. |
