NVDA Screen reader doesn't read items of dropdowns with search when user is hovering them or focusing them with Tab key. Instead it is reading the content of search field. Is it a known issue? Will that be changed in future releases?
Here is an trivial example: https://demo.orbeon.com/demo/fr/orbeon/builder/edit/785b85a843a9910091915ecab6a12a83a8281cc9
Indeed, and unfortunately this is due to issue #3735 of Select2, the component used by Orbeon Forms for the dropdowns with search. On the Orbeon Forms side, this is tracked as issue #4854.
