INavigationPolicy.isNavigable() method
Returns whether or not the given instance should be reachable via keyboard navigation.
Implementors should generally return true, unless there are circumstances under which this item should be skipped while using keyboard navigation. Common examples might include being disabled, invalid, readonly, or purely a visual decoration. For example, while Fields are navigable, non-editable fields return false, since they cannot be interacted with when focused.
