Softkeys do not change to dialog specific ones when native S60 dialog is being opened on top of Qt application

Device: N85
Release: 4.6.x http://qt.gitorious.org/+qt-s60-developers/qt/qt-s60/commit/fe23fd01b4fc61b109bc81bcbac2f832929fb482
Application: Lineedits example
Problem description:

Steps:
1. Launch Lineedits example application
2. Double click # to put editor in predictive text mode and enter some characters f.ex "ade"
3. Press * as long as LSK changes to "Spell" and press it
S60 native dialog opens for typing the user preferred word not found from dictionary. Softkeys chance to LSK=empty, RSK ="Exit" which are Qt application default softkeys. Instead they should change to dialog specific ones LSK("Ok"), RSK("Cancel").
