Accessibility: QtWebEngine accessibility works badly on linux

Our application has multiple web views inside a QML application. Accessibility of those web views is on poor level. Qt seems to at most read the title of the page and a visible content (does not autoscroll, none of the content outside intial view is read out). Clicking items on web page does not produce speech. Also moving focus between a WebWiew and the rest of the UI is incosistent from accessibility perspective.

Accessibility works generally in a different way than in a separate Chrome window having the same content.

A minimal application to reproduce the problem is attached. Using Ubuntu 24.02, Orca 45 (screen reader) and Qt 6.2.2.
