> The following code works fine with no user configuration in Emacs 25.3.  However, it does not work well with the current version of the master branch.  The overlay arrow indicator is not updating as the user moves up or down in the buffer with the keyboard arrow keys.
> 
> Step 1:  Open an Emacs built from the current master branch.
> 
> Step 2:  Got to the scratch buffer and evaluate the code below.
> 
> Step 3:  Maneuver up and down with the arrow keys navigating the code below.  The fringe bitmap indicator should track the vertical cursor position, but it does not work.

Does it update if you type "M-x"?  If it does, you aren't triggering a
