Cursor position behaves badly while using inputMask

If you run the code sample, you'll see that the cursor is blinking at the
end of the TextInput and this is wrong, because only 6 symbols filled.

If you swap two lines of code in the Component.onCompleted handler, the
cursor will be blinking at the very beginning of the TextInput, which is wrong
too.

import QtQuick 1.0

Item {
width: 500
height: 500

Column {
FocusScope {
TextInput {
id: input

height: 20
width: 100
focus: true
cursorVisible: true
}
}
}

Component.onCompleted: {
input.inputMask = "+7 (999) 999-99-99;*";
input.text = "800123";
}
}
