ARIA 1.0 combobox role should be applied to <input>, but ARIA 1.1 combobox role is being applied to a container.

NVDA seems to handle ARIA 1.0 comboboxes ok. But handling ARIA 1.1 comboboxes is broken:

1. In Browse mode NVDA just skips the combobox and its entire contents including <input> inside the container with role=combobox.
2. I can use Tab to focus the <input> inside the container with role=combobox, but when that <input> has focus, switching between Browse/Focus modes doesn't work.
3. The Next Combobox shortcut doesn't work as well (saying «no next combobox»).

The reference example: https://www.w3.org/TR/wai-aria-practices/examples/combobox/aria1.1pattern/listbox-combo.html.

Installed NVDA 2019.1.1, Windows 10.

I am currently reproing it in Chrome Version 74.0.3729.169 (Official Build) (64-bit) and in Firefox 67.0 (64-bit).
