    Description

      when TextEdit's length is above 20000（may be other value）,you could not insert any text.if you insert text,the cursor will turn in circle and the app could do nothing.

      example code is at below.

      import QtQuick 2.0
import QtQuick.Window 2.0

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Scroll")

    Component.onCompleted: {
        for(var loop=0;loop<20000;++loop)
        {
            text.append("12345678901234567890123456789012345678901234567890");
        }
    }

    TextEdit {
        wrapMode:TextEdit.WrapAnywhere
        id:text
        onLengthChanged: print(length)
        text: "TextEdit\n...\n...\n...\n...\n...\n...\n"
    }
}

      I try insert function too.there is nothing differ.
