Comment (by desmith):

 In Pagely's hosting containers, the web root has a bunch of symlinks to
 the "real" WP core files. The code is running in one place, but the core
 files are actually in the path @kimannwall referenced. Maybe something in
 this isn't properly dereferencing symbolic links and so is referring to
 the physical path of the WP core files? (I have a couple test sites and am
 seeing exactly the same thing that others are seeing.)

 @joemcgill: As a short-term thing, what kind of performance problems or
 other negatives are there to defining the filter you described? (I wonder
 if this is something I should deploy for all of Pagely's customers, who
 would presumably have similar issues, presumably wrapped in a version
 check that only adds the filter for 6.3/6.3.1. But if a fix is imminent it
 may not be worth the effort, as opposed to waiting for a core fix.)
