iOS: Accessibility for QTextEdit, QComboBox, Etc. with VoiceOver Isn't Working

To reproduce, use example textedit.
General -> Accessibility -> VoiceOver and switch it on.

Run the example and observe:

1. Text is not readable line-by-line,
instead some numbers are voiced aloud;
2. Some controls like QComboBoxes and etc are not accessible;
3. Etc. issue;

Being familiar in person with several people with
low-vision and severe dyslexia, I'd believe that this a high priority issue.
