 Splitting this out from #33902.

 The first implementation of a combobox with autocomplete search
 suggestions was the link inline toolbar in the Editor, implemented in
 #33301. In a first moment, that didn't work for Safari + VoiceOver, and a
 specific fix was introduced in WordPress 4.5.1, see #36458.
 Worth noting the fix was extensively tested and confirmed to solve the
 issue. That was on El Capitan + Safari 9 + VoiceOver.

 Now, some months later, both the link inline toolbar suggestions and the
 new implementation for the Tags autocomplete (see #33902) are not
 announced correctly when using Safari + VoiceOver, that is macOS Sierra +
 Safari 10 + VoiceOver. Not sure why, sometimes the wrong option gets
 announced. See screenshot below:

 Whether or not it's a Sierra/Safari 10 regression (very likely) a possible
 fix should be investigated. Note: the only example I've found working it's
 the Twitter search suggestion, which is a very similar implementation, so
 investigation should probably start from there. Any feedback welcome :)
