This removal of the label property is in response to the following test error in Course Planner: "TestingLibraryElementError: Found a label with the text of: Course Notes, however the element associated with this label () is non-labellable [<a rel="noreferrer nofollow" target="_blank" href="https://html.spec.whatwg.org/multipage/forms.html#category-label">https://html.spec.whatwg.org/multipage/forms.html#category-label</a>].
