**iPhone 8 14.4, iPadMini 2 12.5.1
Steps to reproduce:
- Run 'quick-accessibility' example project with latest version of Qt 5.15.3.
- Turn on VoiceOver on iOS.
- Tap on buttons and labels.
Expected: Screen reader should read the labels and buttons as it was with Qt 5.15.2.
Actual: Screen reader does not recognize the app content.
NOTE: The same application built with Qt 5.15.2 works as expected.
