Steps to reproduce:

2. Open nano browser example and run it on boot2qt device with '-platform wayland-egl' argument
3. Open qt.io website.
4. Click 'Download.Try.' button and select 'Download Qt installer for linux'
5. Click dropdown for role or phone number, select value and click on it with a mouse.

Expected: The value is selected, as it is with eglfs platform.

Actual: The value could not be selected with the click.
