Comment (by simonpj):

 OK so you are pointing out a bug in CSE.  Very good!  Let's make a ticket
 (#13367) and fix the bug.  I have done that; fix validating now.

 (The same fix is in gridaphobe's patch, but it's orthogonal, so best done
 separately.)

 Back to comment:16. Let's assume that this string-CSE thing makes no
 difference.  Then all my questions in comment:16 remain.  I just want to
 be sure that we are fixing the right problem!
