QWidget with QWebView: focused text input field cannot be seen split view after orientation switch

Preconditions:
Application includes QWidget with QWebView. QWebView includes QLineEdit and some HTML content.

• Tested with pvkb-addressbook test application: select 'Web' button and 'mike's test'. 9 text input fields are visible on screen.

Application is on portrait mode.

Test steps:
1. Tap the text input field at the bottom of the screen ('Field 9' on pvkb-addressbook test application).
--> split view is opened.
2. Type some text so that focused field 9 is visible on split view screen area.
3. Switch orientation from portrait to landscape.

Expected result:
Focused text input field can be seen on split view screen area (e.g. scroll bar can be used to see the focused field).

Actual result:
Focused text input field cannot be seen on split view area: it's not automatically visible on split view screen area and scroll bar does not bring the focused text input field visible.
Error can be reproduced with 'Field 9', 'Field 8', 'Field 7' on pvkb-addressbook test application ('Web' button and 'mike's test') when use case is started from portrait mode.
