Predicted word is duplicated when doing an orientation switch

Precondition: word prediction is active (t9)

Open any Qt application with input widget (i.e. Wiggly).
Type a word: "test" so that is underlines (do not press space, or move cursor with arrow or hard keys)
Turn the device to landscape orientation

--> Input widget should have "test" (non-committed preferably - but that is a different issue)
--> Input has "testtest"
