 introduced an erroneous inline comment for WP_INSTALLING:
It's not quite obvious why do we have define( 'WP_INSTALLING', true ) there (introduced in mu:543 along with the file itself; related: mu:776, mu:952, mu:1603, #23197), but it has nothing to do with ABSPATH, so I suggest removing the comment.
