RadRichTextBox: Cursor moves the first time it blinks after being moved with the keyboard

Steps to reproduce

  1. Click somewhere in the document to move the cursor
    • The cursor starts blinking in the exact location is was moved to after you clicked
  2. Move the cursor with the arrow keys on the keyboard
    • The first time the cursor blinks it moves slightly to the right of the position it was moved to by the arrow key

Unfortunately due to the other cursor jumping bug our users are extremely sensitive to anything that makes it appear like the cursor is not in the position they moved it to.

I attached a gif of this happening with the zoom set to 500% so it is easiest to see but it appears to be a problem at any zoom level 100% or higher.

Hello Rick,

I confirm the issue and we are already working on a fix. The cause behind this behavior is that the default WPF caret does not have any public AP. Thus in order to emulate its behavior, we need to use a replacement one while navigating. The observed offset is a misplacement of the proxy caret. You can track this public item to observe our progress on it.
