Only one line of preview text is shown when Symbian virtual keyboard is open on top of QML TextEdit

Run corkboards qml example (see http://doc.qt.nokia.com/latest/declarative-toys-corkboards.html) with qmlviewer on Symbian^3 device. Click any note that has more than one line of text. Virtual keyboard is opened, but shows only one line of text at a time. One long wrapped line will be shown correctly, the problem only occurs with text lines separated by end of line characters. Now open the virtual keyboard on native Messaging or Notes applications. Up to ten lines of text can be previewed at one time. Tested on top of QtQuick 1.1 branch sha e46c44f9538dbe5b44ce61d3a42403cfa471ae8b.
