Comment (by Ahmed Asar):

Hi Stephen,

Thanks for the detailed report. I was able to reproduce the issue with
divisibleby and center when whitespace is added around the | — while other
filters (like date) handle it fine. This does look like an inconsistency
in the template parser.

Before proceeding, could you confirm which Django version you're using
(exact version, e.g. 4.2.11 or main branch)? Also, would you be open to me
investigating this further and potentially submitting a fix?

I’m happy to help, but I don’t want to step on your toes if you’d like
to work on it yourself.

Best regards!

Hi Ahmed, thanks so much for your swift response!
Yes, please feel free to look into this issue if/when you can -- I doubt I
will find time to work on it in any kind of detail any time soon.
In answer to your question RE: specific Django version, I am using v4.2.4
for the project in question where I noticed this bug. I hope that helps.
Many thanks in advance,
Stephen
