cursorDelegate in TextInput and TextEdit doesn't take the preedit in to account

Cursor delegate is positioned based on the TextInput::cursorPosition and it doesn't take the cursor position in the preedit word in to account. So when a word is in preedit mode, the cursor is always at the beginning of the word.

Try with the following:
TextInput {
id: textInput
anchors.left: parent.left
anchors.right: parent.right
cursorDelegate: Rectangle

}
