This appears to have been resolved in the meantime, or do you
still experience this with any of the actively supported PHP
versions[1]?
BTW, the following part of the reproducer doesn't look right:
MD J:\RAQ_Junc
JUNCTION J:\RAQ_Junc C:\RAQ_Orig
I don't think it's possible to convert an existing folder to a
junction; I went without the MD.

Description:
------------
realpath() returns false for files inside junctions inside a share
accessed using a relative path.
Ok. I _did_ say this was an edge case.
The code below is an batch script utilising Windows NET SHARE and NET
MAP commands to create a drive J: mapped to C:\RAQ_Share and the
JUNCTION program from System Internals to create a junction in that
share.
The last few lines relate specifically to PHP.
Essentially absolute paths are realpath()-able just fine, but relative
paths are not.
Reproduce code:
---------------
@ECHO OFF
ECHO Create Original directory and file.
MD C:\RAQ_Orig
ECHO This is the file. > C:\RAQ_Orig\File.txt
ECHO.
ECHO Create share
MD C:\RAQ_Share
NET SHARE RAQ_Shared=C:\RAQ_Share /UNLIMITED
ECHO.
ECHO Map share
@NET USE J: /D > NUL
NET USE J: \\%COMPUTERNAME%\RAQ_Shared
ECHO.
ECHO Create junction
MD J:\RAQ_Junc
JUNCTION J:\RAQ_Junc C:\RAQ_Orig
ECHO.
ECHO Show the folders.
DIR \RAQ*
ECHO.
ECHO See contents of junction
DIR J:\RAQ_Junc\File.txt
ECHO.
ECHO Use PHP to report realpaths
PHP -v
PHP -n -r "var_dump(realpath('J:/RAQ_Junc/File.txt'));"
CD /D J:\
PHP -n -r "var_dump(realpath('/RAQ_Junc/File.txt'));"
CD \RAQ_Junc
PHP -n -r "var_dump(realpath('./File.txt'));"
Expected result:
----------------
Create Original directory and file.
Create share
RAQ_Shared was shared successfully.
Drop and map share
J: was deleted successfully.
The command completed successfully.
