According to WAI-ARIA 1.1 specification "Authors must ensure an element with role combobox contains or owns a text input element with role textbox or searchbox...". Note, that in our implementation, the text input element is the one that has role="combobox", and does not contain another text input element. This approach is valid for the WAI-ARIA 1.2 specification and also for the WAI-ARIA 1.0 specification .
As it is stated in WAI-ARIA 1.2 "The Guidance for combobox has changed significantly in ARIA 1.2 due to problems with implementation of the previous patterns". Therefore, we will keep the current state, even if it contradicts the WAI-ARIA 1.1 specification.
