This was probably me.  Perhaps a fix wasn't backported?  I notice the
2.5 version of the test changed from the 2.4 version and does a
str.replace rather than changing the last chars of the string.  You
can try using the 2.5 version and my guess is it will work (ie, the
test will pass).  The change is in normalize_output.
