TextField: incorrect input when input method hints enabled

Steps to reproduce:

1. Deploy the app with 'main.qml' (file attached) to device with virtual keyborad (In my case - android), run app;
2. Write something at 1st TextField (I wrote "hereisthetext")
3. Tap at 2nd TextField, write at least one character (I wrote 'j')

Expected result:
get "j" at 2nd TextField
Actual result:
get "hereisthetextj" at 2nd TextField.

console output:
D/libqt_texthints_bug.so(10524): qrc:/main.qml:14 (onEditingFinished): qml: -->> ja. editing finished emited.
D/libqt_texthints_bug.so(10524): qrc:/main.qml:20 (onTextChanged): qml: text changed >> hereisthetextj
