The cursor can get offscreen with QML Text Edit in splitscreen landscape mode

The cursor can get offscreen due to mistranslation of viewport with splitscreen VKB and QML TextEdit.

Steps to reproduce:

1) Start the attached application in landscape mode
2) Click on the "Foobar 6" line to open splitscreen VKB
3) Scroll to the end of the text using right arrow key.
4) Scroll back to the beginning of the text using left arrow key.

Expected result: The view translates so that cursor is visible when cursor would go offscreen.

Actual result: The view translates in the opposite direction, causing even more text to be offscreen.

Note that the view also unnecessarily translates little bit down when going right from the end of the last visible line for the first time in step 3).
