WASM: 'Enable Screen Reader' message overlaps the app content when running Qt Quick examples on Safari

Steps to reproduce:

1. Build any Qt Quick example, e.g.: https://doc.qt.io/qt-6/qtquickcontrols-gallery-example.html 
2. Run the example in Safari 

Expected: The app should work as it does in other browsers

Actual: The app cannot be accessed because the message 'Enable Screen Reader' appears on the screen.

Reproducibility:  100% 

NOTES: It works well in Chrome, Firefox. Widgets examples work without any issues.
