When I click on "collapse," even several times, I still see all the replies in each thread rather than just one entry representing each entire thread.

I am running elogd 3.1.5 on devuan chimaera (bullseye) which I built from source.  I had the same results with 3.1.4 and 3.1.3.

I tried to disable the quick filter just to see if that impacted the behavior, but it didn't.

If there are any other tests I can use to narrow the problem, please suggest them.  Without a working collapse feature, I cannot get a quick birdseye view of, say, all open threads.
