Accepting a proposed word with some other keys does not end the FEP transaction

Use Symbian device (E6/E7) with hardware QWERTY keyboard.
If you are using E7, open the device keyboard.

Open any application with an editor. It does not matter if the editor is QWidget-based, or inside QML application.
Activate word prediction.

Type a word, e.g. 'balloon'.
Press down to popup word suggestion list.
Select 'Ballroom' from the list by pressing 'a' when it is highlighted.
NOTE that word selection works if you use enter, space or tap the selected word.
--> 'balloon' is replaced with 'Ballroom'

Now, press backspace.
--> Editor content becomes 'BallroomBallroo' (with the 'Ballroo' being in predicted state, i.e. underlined)

Looks like that the FEP transaction is not terminated, even though the word is replaced correctly.
