VoiceOver cursor does not navigate and reads out all item of QListView

-When navigating inside QListView Items with voice over, Once focus is outside List view and it is brought back to the listview item, Voice over reads first item of the list view even though cursor is on different item.
-There is no way for voice over cursor to scroll down and reads out items not visible and vertical scroll bar never moves.

Attached is the example which can be used to reproduce it:
Steps:
1. Interact with items in a QListView.

• press 'Control + Option + Shift + down arrow' (Ctr+opt+Shift is default key for voice cursor)
  2. Move VoiceOver cursor on the second item in the QListView.
• press 'Control + Option + down arrow'
  3. Stop interaction with the items.
• press 'Control + Option + Shift + up arrow'
  4. Interact with items in a QListView again.
• press 'Control + Option + Shift + down arrow'
• Now, VoiceOver says information of the first item even if the VoiceOver cursor is on the second item.

Follow step 1 and 2 all the way to the end of all items shown in the list view after that voice over cursor does not scrolls down and reads out other hidden items of QListView.
