Instead it simply copies the full block verbatim into e.g.  *org-src-fontification:python-mode*, as if the extra indent space were a legitimate part of the source.  Normally this wouldn’t be a problem, as faces are attached to keywords.  But for any fontification that depends explicitly on indentation, this leads to incorrect results.  For example, my indent-bars package adds indentation bars via text properties based on absolute column position.  These bars are then offset in the displayed org src block by 2 columns from their correct locations, due to the extra space org has put there.
