### InteractivityChecker `InteractivityChecker` is used to check the interactivity of an element, capturing disabled, visible, tabbable, and focusable states for accessibility purposes. #### Methods ##### `isDisabled(element: HTMLElement): boolean` Whether the given element is disabled. ##### `isVisible(element: HTMLElement): boolean` Whether the given element is visible. This will capture states like `display: none` and `visibility: hidden`, but not things like being clipped by an `overflow: hidden` parent or being outside the viewport. ##### `isFocusable(element: HTMLElement): boolean` Gets whether an element can be focused by the user. ##### `isTabbable(element: HTMLElement): boolean` Gets whether an element can be reached via Tab key. Assumes that the element has already been checked with isFocusable.
