Wrong info in a commitfest page

I happened to notice that

https://commitfest.postgresql.org/21/1962/

shows the "latest attachment" as being from 2018-08-06, whereas
if you look at the thread, the latest attachment is pretty clearly
Heikki's in <16028522-316c-ec71-c065-91a1e1e004a2@iki.fi> of
2018-12-30.  Why is that?

(The cfbot seems to be properly identifying the last attachment,
FWIW.)

            regards, tom lane
