Comment (by afercia):

 In ARIA 1.1 something has changed for the ~combobox` implementation, see
 https://www.w3.org/TR/wai-aria-practices/#combobox

 > NOTE
 > The options for a combobox to popup a grid, tree, or dialog were
 introduced in ARIA 1.1. Changes made in the ARIA 1.1 specification also
 add support for a code pattern that enables assistive technologies to
 present the textbox and popup as separately perceivable elements. both
 ARIA 1.0 and 1.1 patterns are described in the following sections. While
 using the ARIA 1.1 pattern is recommended as soon as assistive technology
 support is sufficient, there are no plans to deprecate the ARIA 1.0
 pattern.

 Seems to me the old ARIA 1.0 example still doesn't work perfectly with
 Safari (version 11.1 at the moment) and VoiceOver, see
 https://www.w3.org/TR/wai-aria-practices/examples/combobox/aria1.0pattern
 /combobox-autocomplete-list.html

 Instead, seems to me the new ARIA 1.1 pattern works better. Some testing
 with various browsers / screen readers combinations  would be greatly
 appreciated, specifically on these three examples:

 ARIA 1.0 autocomplete "list":
 https://www.w3.org/TR/wai-aria-practices/examples/combobox/aria1.0pattern
 /combobox-autocomplete-list.html

 ARIA 1.0 autocomplete "both":
 https://www.w3.org/TR/wai-aria-practices/examples/combobox/aria1.0pattern
 /combobox-autocomplete-both.html

 ARIA 1.1 autocomplete "list" new pattern:

 /listbox-combo.html
