QWebEngineView is not accessible with screen readers

The QWebEngineView is not accessible with screen readers.

Steps to reproduce:

1. Run the WebEngine Widgets Simple Browser Example in Qt Creator.
2. When the application loads, start a screen reader such as NVDA, Narrator or Jaws.
3. Press tab until the focus is inside the webpage.
4. Try to navigate the webpage with arrow keys.

Actual result:

The screen reader doesn't speak at all and doesn't navigate through the web page. Using tab navigates through elements such as links, buttons etc.

Expected result:

The screen reader should navigate through the webpage with arrow keys  similar to how it works with other browsers like chrome, firefox, edge etc. so that the entire page is accessible.

Note: I was unable to test this in Linux and Mac OS but I suspect that this issue persists in other platforms as well.
